Philosophy of Mind Essay Example for Free

Philosophy of Mind Essay Since centuries, our philosophers have been trying to unravel mysteries of our memory, thought processes, different emotions, will power and imaginations culminating into what is known as different intellectual and conscious part of our personality.   Our mind, as our great literary figures have posited, is a stream of our consciousness and is a part of our brains inherent processes. Our mind is a place where our reasoning power gets the shape and takes the practical form. As also said in Indian Vedic philosophy, He who knows the receptacle (Ayatana) verily becomes the receptacle of his people. Mind is verily the receptacle (of all our knowledge). – (Chhandogya Upanishad, V-i-5.) Different studies by our philosophers have been compounded into various theories each delving into the depth of various aspects of our mind processes. Its earliest studies have been found in the works of Zarathushtra, Mahatma Budha, Plato, Aristotle, Adi Shankara and many more ancient Greek and Indian Philosophers.   Many of the pre scientific philosophers based their theories on relationship between the mind and the soul, supernatural elements of faith, having a feeling of closeness with divinity or god, but on the other hand modern theorists based their theories on their research and scientific studies of the brain. These theories rely heavily on the fact that the mind is a phenomenon of the brain and is a tantamount of consciousness. The study of the relationship between the body and mind is the most central aspect to the philosophy of mind, despite of the fact that there are number of issues related to the nature of the mind which does not take into consideration its relationship to the physical body. The most crucial and complex differences of thoughts are arising among different theorists regarding the exact and most appropriate theory of mind. Though various theorists have developed their own different versions to make us understand our own functioning of mind yet as more and more theories are coming up, more and more it is getting difficult to come out with the best theory of all. As all theories are able to capture the intensity of readers to make us understand the core of our mind and thoughts, yet it is very challenging to understand â€Å"Which is the best?† Here I am trying to unravel the mystery to understand which theory-Dualism, mind-brain identity or functionalism is a correct theory to understand all about mind. Dualism is a most important school of thought that has tried to solve the most paradoxical and most important relationship of mind and body problems. It has tried to make several attempts to sure that mind and body in some way or the other detach from each other. Roots of Dualism dates far back to Plato, Aristotle and the Sankhya and Yoga schools of Hindu philosophy but in a most precise way it was understood by Rene Descartes only in the 17th century. His philosophical disposition is based on the fact that the mind is independent in itself and constitutes two different kinds of substances like â€Å"res extensa meaning extended things, physical things† and â€Å"res cogitans means thinking things†, (Descartes, Online Edition ). The thinking things are beyond the dimensions of time and space and are thus separate in itself whereas Property dualists thinks that there are several independent properties known to us. It is quite clear from his disposition that he is trying to explain the importance and concept of soul, giving religious discourse. But in this all, he has tried to explain that there is an interaction of mind in pineal gland, from where there is a control on bodily actions and receive sensory perceptions. But this approach of Dualism is not without criticism as its properties are more of dubious in nature. Their theory is based on religion and their ardent faith but no element of scientific fact is found in this. If we visualize and understands that if there is a soul in our physical body and the soul can have drastic effect then it is quite natural that it should be able to generate new energy to bring the bodies into moment.    It is argued that if the soul exists and it can affect the body then it must be able to create new energy to move the body, but this is sheer violation of the theory of the conservation principle.   Owen Flanagan, in his The Science of the Mind says,†If the mind according to Descartes is not a physical system therefore it also could not have any energy to prove herself but in-order to increase this physical energy, the need of the hour is to get it transferred from other physical system but it is not possibl†e. (Owen Flanagan, pp. 21, Mind creators.com). To overcome the limitations of the Dualism, several philosophers and psychologists began to ignore the very concept and existence of mind itself and by doing so their expectations to touch the cord of mind began to flow towards the realistic parts of our lives. Therefore in the beginning the new generation of philosophers came up with what is known as Type Identity Theory.  Ã‚   They posters the view that though the structure of every person’s brain is similar yet in the brain of every person there are certain differences therefore it is not possible to find oneself in a position of same neurological state. Therefore this theory soon took the shape of Token Taken theory implying that if there are two people having different neuropsychological states, then what is it that brings them into the same mental state? And to this they answered that it is due to the function of those two states only that had created them same. This leads to functionalism theory, which says that, â€Å"Two different brain-state tokens would be tokens of the same type of mental state if the two brain states had the same causal relations to the input stimulus that the organism receives, to its various other mental states, and to its output behavior†. (Functionalism, online edition). In simple words, he said that there were supposed to be two thoughts, which are same, and all of the inputs, internal and external, lead to the same output. With this statement, psychologists tried to bring all the conditions of the mind set in equilibrium. This leads to the functionalism theory. Though there are several problems to this approach too yet we can very say that if this theory of functionalism is adopted, it will take us into next major breakthrough, but all is not well with Functionalism too as it failed to explain in clear terms the fact that even if there are conditions of different physical states which gives different material phenomenon, then there is no possibility of different physical structures to regain equality.  Ã‚   . While there is a great controversy to come at the concrete conclusion about which one is correct theory of mind,, but it is a matter of fact that functionalism is the most popular theory among scientists as well as philosophers of today. According to this theory, all the aspects of mental state like beliefs, pains, hopes, fears, etc. depends and are divided on the bases of their activity and are characterized by the jobs they do, or in other words according to the functions that they perform. Just like computers understands the main idea behind our thoughts process in the same way our brains captures our thought processes from our mind and induces us to act accordingly.

breast cancer Essay -- essays research papers

Breast Cancer   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Breast cancer is the most common cancer among women. The American cancer society estimates that in 2002 about 192,200 new cases of breast cancer will be diagnosed among women in the U.S. alone. Breast cancer also occurs in men. An estimated 1,500 cases will be diagnosed among men. In 2002, there will be about 40,600 deaths from breast cancer in the United States.   Ã‚  Ã‚  Ã‚  Ã‚  What is breast cancer? Breast cancer is a malignant tumor that has developed from cells of the breast. To make it easier I’ll put it this way. When the body needs new cells they will divide or reproduce. Sometimes the cells grow and divide out of control, which creates a mass of tissue called a tumor. Now if the cells that are growing out of control are abnormal and don’t function like the body’s normal cells the tumor is then called malignant or cancerous. Cells from the malignant tumors can invade and damage nearby tissues and organs. They may also travel through your blood stream or lymph system to other parts of your body. If the cells are normal cells the tumor is called benign or non cancerous. This Disease occurs mostly in women, but dose occur rarely in men. There are many stages of breast cancer. Stage 0 breast cancer is when the disease is localized to the breast and lymph nodes. Stage 1 is when the cancer is smaller than 1 inch across and hasn’t spread. Stage II is one of the following: the tumor is less than one inch but has spread to the underarm lymph nodes or the tumor is between 1-2 inches without spreading. Advanced breast cancer results after cancer cells spreads to the lymph nodes and to other parts of the body. Stage III breast cancer is also called locally advanced breast cancer. The tumor is now larger than 2 inches and has spread to the lymph nodes under the arm, or a tumor that is any size with cancerous lymph nodes that attach to each other or surrounding tissue.   Ã‚  Ã‚  Ã‚  Ã‚  Stage IIIB breast cancer is a tumor of any size that has spread to the Skin, Chest wall or internal mammary lymph nodes, which are located beneath the breast and inside the chest.   Ã‚  Ã‚  Ã‚  Ã‚  Stage IV breast cancer is defined as a tumor that has spread to places far away from the breast, such as bones, lungs or lymph nodes.   Ã‚  Ã‚  Ã‚  Ã‚  There are... ... no way to prevent breast cancer but there are a ton of things you can do to help reduce your risks of getting it. You should always eat foods high in fiber. Fiber helps reduce the amount of circulating estrogen in your body. Eat plenty of fruits and vegetables, also include soy in your diet. Studies say that soy may inhibit the development and growth of cancer cells. Limit the fat in your diet, limit alcohol, and stay physically active. The Nurses Health Study found that women who exercise for at least 1 hour a day reduce their breast cancer risk by 18 %. You should also maintain a healthy weight and avoid exposure to pesticides. Because the molecular structure of some pesticides closely resembles that of estrogen. This means that they might attach to receptor sights in you body. It is known that women with high levels of pesticides in their breast tissue have a greater breast cancer risk.   Ã‚  Ã‚  Ã‚  Ã‚   Although there are many different things that go along with breast cancer. This paper really helped me understand more about the subject and helped me know some of the signs that I need to look for and ways to help me reduce the risks of getting breast cancer.

How Science and Technology Is Going to Change the Future

how the science and technology is going to change the future ! Introduction Science and technology is a systematic representation which helps to build or organize one's knowledge and to acquire intelligence with some experiments and explanations. The words â€Å"science and technology† are derived from the latin and greek words ‘SCIENTIA and TECHNOLOGIA'. This topic is explained with some details below. History of Science and technologyThe history of science and technology is indentified as a field of history which examines how HUMANITY understands the natural world which is called science and their ability to manipulate it which is termed as technology. Before the word scientist was invented in 1833 , scientists were known as Natural Philosophers. Greatest achievements and inventions The first and foremost invention of mankind is nothing but a â€Å"WHEEL† which further passed down in the inventions of screws , levers etc.By the mid 20th century humans had achiev ed a mastery in technology by making mankind sufficient to leave the atmosphere of the earth and explore space , another important invention is satellite. The first artificial satellite SPUTNIK-1 was built by SOVIET UNION which was launched on 4th OCT 1957 after revolving around the earth 1440 times which is equal to 60 million miles for 3 months burnt to ground on 4th JAN 1988 which is one of the greatest achievement in human history.Harzadous Developments The growth and development of the harzadous side of science and technology began at the start of the world wars , the invention of ZEPPELIN, a type of rigid airship and other warcrafts such as TANKS, SUBMARINES and BATTLESHIPS caused unestimatable loss to humanity around the world . To tackle the enemies new research and inventions were brought in which resultd in the harzadous poison ‘POLLUTION' that caused damage to our earth and us at present. Welcome to the FUTURE !!!Technology developments tends to make the life for hu mans ‘STRESSLESS'. Technology upgrade concept such as flying cars , bullet trains , cloud computing enables humanity to reach their destinations swiftly and complete the works fastly thereby saving time and energy . Therefore Technology development helps the future generations fulfilling their needs. Greener IDEAS! Pollution in the world can be controlled by some of the following methods like RECYCLING , REUSING and preventing the methods and inventions that cause Pollution.Technology deveolpments are profitable to future generations when it combines with the greener ideas! , for example in 2008 the world's first bio degradable computers â€Å"the IAMECO† was built from the waste products of lumber and pulp industry in Ireland. Conclusion From these things we can conclude that technology development is needed but development which creates a pollution free earth is appreciatable. Therfore the final conclusion is â€Å"GREENER THE WORLD BRIGHTER THE FUTURE†

Killer Whale Dorsal Fin Collapse

For some time, theres been a heated debate about why  killer whales in captivity have dorsal fins that are flopped over or collapsed. Animal-rights activists say that these fins collapse because the conditions under which killer whales — or  orcas — are held in captivity are not healthy. Others, such as water parks that keep killer whales in captivity and use them in theme-park shows, argue that there are no health threats to killer whales held in captivity and that dorsal fin collapse is natural. The Lowdown on Dorsal Fins All killer whales have a dorsal fin on their back, but the males dorsal fin is much taller than a females and can grow up to 6 feet tall. Despite the fact that the dorsal fin is very straight, it is supported not by bone but a fibrous connective tissue called collagen. All males in captivity have collapsed dorsal fins, but the condition, also known as dorsal fin collapse, flaccid fin, or folded fin syndrome, ​does occur in many captive females. Scientists are not certain why orcas have dorsal fins or what purpose the appendages serve. But, there is some speculation.  Whales Online  says that the large dorsal fin enhances the hydrodynamics of killer whales: (The dorsal fin) helps them slip through the water more efficiently. Similar to the ears of elephants or the tongues of dogs, dorsal, caudal and pectoral fins also help eliminate excess heat during intense activities such as hunting. Orca Live  agrees that the fins help regulate a killer whales body temperature: Excess heat, generated as they swim along, is released into the surrounding water and air via the dorsal fin — much like a radiator! Though there are different theories about their specific purpose, its a fact that dorsal fin collapse is far more prevalent in whales that are held in captivity. Dorsal Fin Collapse A wild orca often travels far, and quickly, in deep water. The water provides pressure to the fin, keeping the tissues inside healthy and straight. One theory as to why dorsal fins collapse in captivity is because the orca spends much of its time at the water surface and doesnt swim very far. This means that the fin tissue gets less support than it would if the orca were in the wild, and it starts to fall over. The whales also often swim in a repetitive circular pattern. Other potential causes for fin collapse may be dehydration and overheating of fin tissue  due to  warmer water and air temperatures, stress due to captivity or changes in diet,  reduced activity that causes low blood pressure, or age. SeaWorld of Hurt, a website operated by animal rights organization PETA, takes this stance, noting that dorsal fins of captive whales likely collapse Because they have no space in which to swim freely and are fed an unnatural diet of thawed dead fish. SeaWorld claims that this condition is common — however, in the wild, it rarely ever happens and is a sign of an injured or unhealthy orca. SeaWorld announced in 2016 that it would stop breeding whales in captivity immediately and  phase out killer whale shows  at all its parks by 2019. (In San Diego, the shows ended in 2017.) The company has said, however, that the shape of a killer whales dorsal fin is  not an indicator of its health. The dorsal fin is a structure like our ear, said Dr. Christopher Dold, SeaWorld’s head veterinarian: It doesnt have any bones in it whatsoever. So our whales spend a lot of time at the surface, and accordingly, tall, heavy dorsal fins (of adult male killer whales) without any bone in it, will slowly bend over and assume a different shape. Wild Orcas While less likely, it is not impossible for a wild orcas dorsal fin to collapse or become bent, and it may be a trait that varies among whale populations. A study of killer whales in New Zealand showed a relatively high rate — 23 percent — of collapsing, collapsed, or even bent or wavy dorsal fins. This was higher than that observed in populations in British Columbia or Norway, where only one male from the 30 studied had a fully collapsed dorsal fin, the study said. In 1989, the dorsal fins of two male killer whales collapsed after exposure to oil during the  Exxon Valdez  oil spill—the whales collapsed fins were thought to be a sign of poor health, as both whales died soon after the collapsed fins were documented. Researchers have theorized that dorsal fin collapse in wild whales may be due to age, stress, injury, or altercations with other killer whales.   Sources Matkin, C. O., and E. Saulitis. 1997.
