Aristotles Concept of Teleology Essay - 880 Words

Aristotles Concept of Teleology In his Physics, Aristotle examines the theories and ideas regarding nature of his predecessors and then, based upon his own ideas, theories and experiments, argues against what he believes are incorrect conclusions. One idea that Aristotle argues specifically is teleology. Teleology is the idea that natural phenomena are determined not only by mechanical causes but by an overall design or purpose in nature. In this essay, I will examine what Aristotles concept of teleology was and look at why he held this conception. First, lets talk about what we mean by teleology. Teleology is the study of ends, purposes, and goals. The word comes from the Greek word telos which means quot;endquot; or†¦show more content†¦He maintains that organisms develop as they do because they have a natural goal or telos in Greek. â€Å"Nature†, writes Aristotle, is â€Å"a ‘principle of motion and change †(Physics, 200b1), where â€Å"motion† or â€Å"movement† (or change as we discussed in our classroom) describes the â€Å"fulfillment of what exists potentially, in so far as it exists potentially†(201a) in a thing. But is there any reason for saying nature has a goal? Why cannot the rain rain and the sun shine, not because the sky is cloudy or clear but just by chance? Empedocles argued for a theory of natural selection on the basis of chance. The survival of the fittest means that those who happen to be more fit survive longer. The less fit perish. Aristotle rejects any theory of evolution. Things either occur by chance or they occur â€Å"always or for the most part, â€Å" which is the opposite of chance. You must admit that things that occur â€Å"always or for the most part† occur either by chance, or not by chance. If they occur not by chance, then they occur for a purpose. Lets take the example of monsters. Monsters occur by chance because they are not among those things that are always or for the most part. Man, on the other hand, survives because he is meant to survive. To argue that he is a result of chance is to argue that he does not exist always or for the most part, but only sometimes. This, of co urse, is absurd. Because most things in nature seem to occur most of the time and exhibit a pattern of changeShow MoreRelatedAristotles Concept of Teleology885 Words   |  4 PagesAristotles Concept of Teleology In his Physics, Aristotle examines the theories and ideas regarding nature of his predecessors and then, based upon his own ideas, theories and experiments, argues against what he believes are incorrect conclusions.

Flamenco Essay - 2200 Words

To what extent is Flamenco iconic of Spanish cultural identity? The passionate imagery conjured by the flamenco art form of colour, life and exoticness are characteristics often associated with perceptions of Spain. In saying that, within contemporary society flamenco has now become an icon of â€Å"Spanish culture† however the degree to which its resemblance accurately portrays Spanish, or more specifically the Spanish nation’s cultural identity is limited due to it being more an expression of regional identity that has been portrayed to be a national symbol (Malefyt 1998).

The ability to further appropriate for personal benefit can be seen in Franco’s eagerness to use unifying Spanish images during his dictatorship of 1939-1975 where he adopted flamenco into the nationalist discourse known as La Hispanidad which effectively led the process of deregionalisation through internal migrations from Andalusia to northern provinces (Paetzold 2009, p.209). The Franco regime deployed messages through flamenco as they used film as a means of disseminating propaganda to the masses (Hayes 2009, p.94) and Spanish scholars sought to make flamenco a symbol of national identity (Washabaugh 1997).

Empiricism Vs. Positivist Theory Of Knowledge - 1053 Words

Epistemology is the branch of philosophy that evaluates the acquisition, limitations, and origins of human knowledge. One of the theories found in epistemology is the theory of empiricism. Empiricism is the belief that knowledge is gained through experience, that there is no such thing as â€Å"innate knowledge,† or knowledge that one is born with. Empiricism stands in stark contrast to the rationalist theory, the belief that humans possess innate knowledge, and that one can have knowledge, without sensory information or experience, through reason. In this paper I will evaluate the theory of empiricism, comparing it to rationalism and discussing advantages and disadvantages of the empiricists perspective on the acquisition of knowledge, and then I will discuss why I consider empiricism the superior theory of knowledge. One of the main critiques of the empiricist theory is that it is derived strictly from sensory information. Any knowledge that we may possess is strictly from t he experiences we have had in our lifetime. This is a problem that rationalists have with empiricism. Rene Descartes, mathematician and father of modern philosophy, argues that our senses cannot be trusted, and that they are easily deceived (Epistemology, slides 26-28). Not unlike Descartes, it is common for mathematicians to subscribe to the side of rationalism in regard to the acquisition of knowledge.

string(136) " adorn tracts and terraces Application of Recycled Paper Puting the paper in the recycle bin helps re-create paper from bing resources\." Recycling is a procedure where waste or used merchandises are reproduced into new merchandises. A merchandise which has served its ain intent will be discarded, and recycling is an attempt to widen the usage life of a merchandise, therefore conveying a batch of benefits to humanity and the female parent Earth. Most points around us are reclaimable, although there are specific techniques used to recycle different stuff, including metal, plastic and paper. We will write a custom essay sample on Why Is Recycling Important Environmental Sciences Essay or any similar topic only for you Order Now The full procedure of recycling involves 3 basic stairss. The used stuff has to be collected, and so sorted harmonizing to its stuff. The 2nd measure involves bring forthing useable goods from the sorted points. After the goods were produced, the last measure requires selling of the reproduced goods to the general mass, consumers or a specific market. As the reproduced goods are sold and reused, the full procedure of recycling is complete and will do manner for another rhythm to come. Why is recycling of import? Recycling helps continue the environment in add-on to supplying more useable objects to people without the demand for excess resources. Its importance can be seen in multiple ways. Below are the grounds in which recycling can be good: Recycling Saves the Earth Recycling a stuff can assist continue the environment. For illustration, recycling the paper can ensue in paper production without extra tree falling. By recycling more paper and selling it to consumer, more documents can be used without farther damaging the forest than its current rate of tree falling. Recycling Saves Energy Recycling a stuff takes less energy than to bring forth an point from virgin stuffs. For illustration, an aluminium merchandise uses both the aluminium and the immense sum of energy to bring forth it from natural ore. Therefore by recycling an point made of aluminium, we can recycle the metal once more and besides salvage on the immense energy which helps continue the environment. Recycling Helps Mitigate Global Warming and Reduce Pollution One of the biggest benefits of recycling is salvaging energy. Energy salvaging consequences in less emanation of C or nursery gases which are a byproduct created by energy production, which are damaging and harmful to the environment if released to the ambiance. Recycling Reduces Waste Products in Landfills Waste which are non recycled normally ends up in the landfill. It is here that the waste are left to decompose or decomposed, and this may take many old ages of even coevalss to to the full break up. More and more waste are being sent to the landfills, and if recycling does non take topographic point, the landfill may be right behind our places in the hereafter. Recycling Helps you Save Money Recycled merchandises normally cost less. Using bing stuff and a batch less energy, recycled merchandise can be sold for a fraction of the same point created utilizing virgin stuffs. Apart from that, selling waste for recycling intents converts refuse into utile hard currency. Recycling can besides be done at place, and taught to the kids as a good wont to be nurtured. Biodegradable waste can be used as fertiliser for workss. Creativity goes a long manner in salvaging money and salvaging the planet Earth. Recycling becomes progressively of import in a universe where the population is dining. More and more merchandises are being churned out to consumers. If these merchandises are non recycled at the terminal of the merchandise life, it will take coevalss to interrupt down or break up. Applications of Recycled Materials Application of Recycled Glass Man has found ways to recycle glass. This in fact, is extremely recommended and good to the fabrication line as it is easier to bring forth and be less. Crushed glass known as cullets, thaws easier and faster and cost less than the natural stuffs used to bring forth glass. This pattern is endorsed by the US Environmental Protection Agency as a better and greenish manner to bring forth glass. Common Non-container Uses Harmonizing to Glass Packaging Institute, recycled spectacless are best to be used for its initial intent before it was being sent for recycled. For illustration, glass bottles are best recycled to be made into glass bottles, and those which does non measure up in the container fabrication criterions can be channeled to other uses such as fibreglass. ( See References 2 ) Aggregate Materials Recognize it or non, we ‘re driving over glass every twenty-four hours in our lives. Parking tonss and concrete paving has grounded glass composing. Grounded glass as an effectual base stuff enhances the public presentation of the crushed rock in the mix, and sometimes is independent of other stuffs when used as a base. Glass-phalt is a stuff applied to doing roads, including airdrome tracks and main roads, doing the surface to hold higher clash coefficient, less slippy and less likely to check. Glass-phalt is made of recycled glass. Recycled glass is besides used to do glass beads, which in bend is used to do brooding pigment on the route. Abrasive Media Harmonizing to the Clean Washington Center, the use of recycled glass as scratchy media is known as â€Å" basal burden market † . It is verified that recycled glass has equal or better quality than traditionally used scratchy media, such as aluminium oxide or walnut shell. This makes recycled glass extremely competent in the surface readying of fabricating equipment constituents and even ships. Furthermore, less recycled glass is required to bring forth the same occupation when compared with use of traditional mineral. Furthermore, glass has the advantage of being non-detrimental to wellness with no silicon oxide exposure dust. Landscaping Green-scaping is a term used for landscape merchandises which are manufactured utilizing recycled glass. Glass does non absorb wet unlike its wooden opposite number, therefore bettering H2O bringing. It besides comes in assorted colourss to take from. Manufacturers use crushed porcelain in concrete slab in add-on to the recycled glass to adorn tracts and terraces Application of Recycled Paper Puting the paper in the recycle bin helps re-create paper from bing resources. This diverts the waste meant for landfills into useable merchandises which uses less energy, H2O and stuff to bring forth. How Much Paper is Recycled? How much paper is really recycled? Research shows that the sum of paper being recycled has reached record degrees. Harmonizing to the Paper Industry Association Council, â€Å" In 2008, 57.4 per centum of the paper consumed in the U.S. was recovered for recycling. This impressive figure peers 340 lbs for each adult male, adult female and kid in America. † Limits on Paper Recycling Documents are limited by the fibre it contains. As paper is recycled each clip, it breaks down into mush. This can be done for a maximal six or seven times. The fibre so will be shortened each clip until it is non useable. Office Grade Paper Office class documents are the highest quality documents in the rhythm of recycling. Its quality and firmness plus its hardy fibres, this type of paper are frequently recycled back into its initial class. However, decoloring is required to reproduce its whiteness. Newspaper Documents used for newspaper are frequently low choice paper, therefore it can non be recycled into better quality paper. As paper can non be upgraded through recycling, the paper used for newspaper are frequently recycled back into its initial use or lesser class Cardboard Cardboard, whether corrugated or pressboard, is made of the lowest quality paper. If it ‘s of all time recycled, it can be used for packaging. Producing boxes or cartons is ideal, as the colour or brightness dulls overtime as it is recycled, and boxing boxes like cartons seldom considers colour as an of import factor. Tissue Tissue can be a signifier of recycled merchandise. Since strength of paper is non an issue, unserviceable fibres are normally used for bring forthing tissue. Other Uses for Recycled Paper There are many other merchandises that are produced utilizing recycled paper: java filters, nappies, egg cartons, shoe boxes, serviettes or insularity. Application of recycled Plastic Recycled plastic can be used in many applications and merchandises, such as packaging, building or car constituents. Boxing Recycled PET or HDPE is chiefly used in packaging by retail merchants. Household names such as Coca Cola, The Body Shop or M A ; S normally use recycled plastic in some of their merchandises. Use of recycled plastic helps show a trade name image towards committedness to sustainable resource usage. Construction Recycled plastic is used a batch in building stuffs, such as drainage pipes, ducting or flooring. It is innovated into scaffolding boards or curbstones, where its lastingness and weight has superior benefit to Health and Safety intents. Landscaping Landscaping utilizations recycled plastics to be made into paseos, breakwaters, pontoons, Bridgess, fencings and marks. Durability, low care, vandal opposition, and its opposition to decompose are all cardinal grounds for plastic being used. Textile fibre / vesture Polyester fleece vesture and polyester filling for eiderdowns is often made from recycled PET bottles ( e. g. soft drink and H2O bottles ) . Polyester fibre is the biggest individual market for recycled PET bottles worldwide. Street furniture Street furniture, seating, bins, street marks and plantation owners are often made from plastic. They are cost competitory and immune to hooliganism. Local governments and schools are able to show recycling in action by stipulating recycled merchandises. Bin liners/ garbage pokes Plastic movie from beginnings such as palette wrap, bearer bags, and agricultural movie are made into new movie merchandises such as bin line drives, bearer bags and garbage pokes on a big graduated table. Application of Recycled Metal The maps of metals like steel, Cu, and aluminium was revealed 1000s of old ages ago. Their belongingss and features of strong, lasting, ductile and high conduction are extremely of import in a broad scope of merchandises today. However, metals are resources of the Earth which has finite measure and non replenish-able. Metallic element sedimentations are non-renewable resources that will run out if it is continued to be mined at the current rate. Therefore, it is extremely of import to recycle metals. Metallic elements can be recycled without losing any their key belongingss. Inefficient recovery of metals from industrial and consumer waste increases the force per unit area on the non-renewable resources of the Earth from which they are extracted. Discarding metal is bad for the environment due to the release of metallic atoms in the ecosystem. Recycling and metal recovery from the waste watercourse is indispensable in continuing valuable resources and the environment. Recycling metals are effectual because they can be recycled for infinite times, doing them highly friendly to the environment. Metallic elements differ from polymer plastics in a manner that the features are maintained irrespective of the physical or chemical signifier, although it might be dearly-won. Aluminum The extraction of aluminium from its ore requires immense sum of energy. To pull out aluminium from aluminum oxide is a complex procedure. Recycling aluminium merely takes about 5 % of the energy used compared to bring forthing it via excavation, and therefore merely releases 5 % of the CO2 emanation. This in add-on decreases the sum of waste being transported to the landfill. A recycled aluminium can salvage adequate energy to run a telecasting set for 3 hours. For illustration, recycling 1kg of aluminium saves up to 6kg of bauxite, 4kg of chemical merchandises and 14 kWh of electricity. Steel Iron is extracted from Fe ore which is common and extremely abundant. Normally found in a combined signifier with O or other elements like sulfur or C. Huge sums of energy required to pull out the Fe from the ore. Over 11 million dozenss of Fe and steel bits are produced every twelvemonth. From this sum 70 % are recovered. Of the staying measure, 60 % is sent to the landfill. Every ton of steel recycled can salvage 1.5 dozenss of Fe ore, 0.5 dozenss of coal, 40 % of the H2O used in production, 75 % of the energy required to pull out steel from the natural stuff, 1.28 dozenss of solid waste, lessening in air pollution emanation of up to 86 % , and decrease of H2O pollution release by 76 % . Recycling Metallic elements / Other Metallic elements to Look Out For Copper, Ni, brass, lead, gold, Ag, etc. can all be recycled. Since these metals are all rather valuable merely a smaller measure is in circulation. The recovery of these metals is sometimes ignored particularly when they are used in families and these points are disposed of by the homeowners. Application of Recycled Oil Did you cognize? That used, second-hand oil can be farther re-refined into base stock for lubricating oil? And besides, if you recycle merely 2 gallons of used oil, it is sufficient to bring forth electricity to run the mean family for about 24 hours. Cars, like many transit vehicles, are an indispensable portion of life for many of us. What is done with the used oil, whether to dispose of it or to recycle it plays a important function in equilibrating our desire for convenient transit with our hope for a clean and healthy environment for our kids? We are all familiar with recycling newspapers, aluminium tins, glass and plastic bottles, but many of us are non even cognizant of the attempts carried out by elephantine crude oil industry to advance used motor oil for recycling, for illustration, supplying convenient aggregation sites for the intent of maintaining used motor oil out of our H2O supplies and doing certain that the oil goes back into the recycling rhythm. Curiously plenty, even after it has been drained from an engine, motor oil retains some of its value. The oil collected can be recycled to salvage energy. Many establishments, schools or workss process the used oil for electricity coevals. Some workss even process it to be used for engine oil once more. As consumer, we can direct our used oils for recycling by taking it to the aggregation centre. If our autos are taken to the auto service centre, we can be reasonably certain that the oil will be recycled after they change. Additionally, we can do a difference by recycling the oil from our auto, truck, bike, boat, recreational vehicle or lawnmower. By dropping off our used motor oil today we help forestall pollution and conserve energy for a safer and healthier tomorrow Recycling used motor oil maintain oil out of landfills and ensures that this oil is available for re-use, reconditioning, recycling or re-refining. In fact, the best oil for the interest of environment is the longer permanent oil, doing certain that less oil is generated. Equally much as over 380 million gallons of used oil is recycled every individual twelvemonth harmonizing to the U.S. EPA, which is tantamount to over 50 per centum of all motor oil purchased yearly. Currently, used motor oil can be re-used or recycled in one of the three known ways – reconditioning, recycling or re-refining. Re-refining With modern and sophisticated method, refinement can be done with accurate provender and rigorous quality control. Used motor oil can be processed to take any drosss so it can be reused as a base stock for the new lubricating oil. This efficaciously extends the lifetime of the oil, doing it reclaimable for many times without directing it to the landfill. At the present, less than 15 % of used motor oil is refined and the consumer demand for refined used motor oil is low, doing it difficult to prolong for concern. It is of import to observe that the purchased refined used motor oil comply with the oil specifications as set by the vehicle maker. Reconditioning In some industries, oil is filtered or clean in commercial graduated table machine. Although it may non change over the oil back to its premier quality, it can take drosss and cardinal additives can be added to widen its life and maps. Re-Use and Reprocessing Both motor oil and fuels are petroleum merchandise. As lubricator, when the oil has ceased operation, it can be reused to be burned as fuel without the demand for farther intervention. Water and certain atoms may necessitate to be removed earlier before the oil can be burn for electricity coevals. 74 % of all oil recycled in the United States of America is for the intent of fuel burning in turbines, incinerators, power workss, cement kilns and fabrication installations. An extra 11 % of used motor oil is burned in specifically designed industrial infinite warmers. This creates a valuable signifier of energy, which helps our economic system by avoiding the demand to polish new commercial warming oil from imported petroleum oil.

What factors play into the choice to remarry? What are some of the issues remarried couples face? What would help them cope with these possible issues? Answer: Reasons for divorce From the last 50 to 60 years, the divorce is becoming an interesting problem all over the world (Scott et al. 131). Some of the principal reasons for divorce are: The lack of faithful commitment Getting married at an early age Excessive arguments on simple matters Disappearance of the intimacy Illogical and unreasonable expectations Absence of good equity in the relation Lack of proper employment and earnings to run the family Presence of different priorities and different interests between the couples Severe abuse Reasons for remarriage After the divorce, there are several factors that play a fundamental role in provoking the person to step towards remarriage. Those are: The person may again fall in love with someone who stood there during a tough time and wanted to spend the rest part of the life with the beloved. The person may feel to be mature enough to take self-care as well as the care of the other person. The person may feel to be financially stable to be engaged to a new relation. Being financially stable, the behavior will also turn towards positivity. Issues with remarriage and management Though the remarriage sounds better, there are issues after this. The remarried couple faces several questions regarding their past life. Moreover, the maximum problem is a face from the part of the children who find difficulty in adjusting to their new parents and often abuse them (McNamee et al. 866). It is said that the time has the healing power. Similarly, this adverse condition can also be recovered up by careful and loveable understandings between the family members.

Mycorrhizae free essay sample

Mycorrhiza is a specialized fungus in the soil which forms close associations with the roots of a vascular plants * In other temperate and boreal successional systems arbuscular mycorrhizal fungi are the primary mycorrhizal associate in early succession, whereas in older soils the main associates are ectomycorrhizal fungi (Piotrowski, 2008). Arbuscualar Mycorrhizae: Arbuscular mycorrhiza (AM) is the predominant and ancestral type of mycorrhiza in land plants. It’s root cells have arbuscules (tree like structure, highly branched hyphae inside plant cells) and vesicles in most species Its occurrence in a vast majority of land plants and early-diverging lineages of liverworts suggests that the origin of AM probably coincided with the origin of land plants. Classes include Archaeosporales, Diversisporales, Glomerales, Paraglomerales, part of the phylum Globermycota, and part of the kingdom fungi (species grow Arbuscular Mycorrhizae) * Fossil evidence and DNA sequence analysis by mycologists show arbuscular mycorrhizae first appeared approximately 400-460 million years ago. We will write a custom essay sample on Mycorrhizae or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Arbuscular mycorrhizas are found in 90% of all plant families, and occur in many crop species. How it Works: * Plant nutrients which are concentrated with nutrients are taken by hyphae and then released into the root cells of vascular plants. Nutrients can also be stored in the root of the fungus and used in the future when the nutrients are needed, such as low temperatures or season fluctuations. * Arbuscular mycorrhizas are mycorrhizas whose hyphae enter into the plant cells, producing balloon-like vesicles or dichotomously-branching arbuscules. Arbuscular mycorrhizae are known to be heterkaryon, goining through both asexual and sexual reproduction. * The hyphae of arbuscular mycorrhizal fungi produce the glycoprotein glomalin, which may be one of the major stores of carbon in the soil. Arbuscular mycorrhizal fungi have (possibly) been asexual for many millions of years and, unusually, individuals can contain many genetically different nuclei (a phenomenon called heterokaryosis). * The fungal hyphae do not in fact penetrate the protoplast (i. . the interior of the cell), but invaginate the cell membrane. The structure of the arbuscules greatly increases the contact surface area between the hypha and the cell cytoplasm to facilitate the transfer of nutrients between them. Ectomycorrhizae * Ectomycorrhizas, or EcM, are typically formed between the roots of around 10% of plant families, mostly woody plants including, eucalyptus, oak, pine, and rose * Families and fungi belonging to the Basidiomycota, Ascomycota, and Zygomycota. Ectomycorrhizas consist of a hyphal sheath, or mantle, covering the root tip and a hartig net of hyphae surrounding the plant cells within the root cortex. In some cases the hyphae may also penetrate the plant cells, in which case the mycorrhiza is called an ectendomycorrhiza. Outside the root, the fungal mycelium forms an extensive network within the soil and leaf litter. Nutrients can be shown to move between different plants through the fungal network. Carbon has been shown to move from paper birch trees into Douglas-fir trees thereby promoting succession in ecosystems. Benefits of Mycorrhizae * AMF affect phosphorus cycling, aid seedling establishment of many plant groups, help maintain plant diversity, and strongly contribute to soil stabilization and carbon storage through soil aggregate formation * Experiments have shown mycorrhizas can increase the uptake of plant nutrients such as nitrogen and phosphorous when they are at low concentrations or in insoluble form in the soil * Improve crops without being indispensible * Make nutrient uptake from poor soil more resourceful Mycorrhizas can increase the absorption of plant nutrients when they are at low temperatures or insoluble in the soil * The plant supplies the fungus with carbon compounds, including hexose sugars which are sugar alcohols which increases the plant cell permeability. * Carbon can be transferred between plants because mycorrhizae grow and attach to many different roots of plants of different species
