The basic principle of biological determinism is to search for a biological mechanism that explains a human behaviour or a form of society. (Little, McGivern n.d., p.93) Biological mechanisms can be gene’s, instinctual behaviour, or evolutionary advantages. (Little, McGivern n.d., p.93) The first step of biological determinism is to identify a trait that occurs throughout time and different cultures. Secondly, they search for the universal trait which is believed to be coded in the DNA of those who share the trait. Lastly, researchers develop a theory as to how the trait serves an evolutionary advantage. (Little, McGivern n.d. p.93) The issue with biological determinism is that it is difficult for a biological mechanism to account for the wide variety and circumstances and social phenomena. (Little, McGivern n.d., p.94) The trait of intelligence it is difficult to explain due to the variations of intelligence: logic, linguistic, musical, as well as social intelligence. These mechanisms also do not account for the circumstances of intelligence. For instance, certain individuals are socially intelligent at bars or other get-togethers, though they may struggle at maintaining intimate relationships. These issues with biological determinism …show more content…
However, it is difficult for biological mechanism to account for the wide variety of social phenomenon and circumstances. The new-eugenics movement, however, has found a practical use for biological determinism, by uncovering mechanisms that lead to disease and disabilities. It is important to understand that the conclusions drawn from these experiments are extremely broad to avoid creating stereotypes and prejudices. Biological determinism may be limited in predicting human behaviour, however, with careful experimentation, it can uncover predispositions to disease and disability allowing for preemptive medical
Determinism, a doctrine that all events, including human action, are ultimately determined by causes external to the will, especially when up against nature. An influential component found in naturalistic writing, London, Garland, and Crane each lend their writing to this movement, realism, modeled after the writings of Darwin, Marx, and Freud. Determinism, generally pessimistic, presents itself in the form of Koskoosh, an elderly, blind man left to die by his tribe. This indigenous, cold-climate tribe embraces the “survival of the fittest” mentality. Simply surviving was a burden for this tribe and they certainly did not have the resources to sustain a dependent person. The story mentions the good times when the dogs and people were fat, as

The history of harmful eugenic practices, spurring from the Nazi implementations of discrimination towards biologically inferior people has given eugenics a negative stigma (1,Kitcher, 190). Genetic testing, as Kitcher sees it through a minimalistic perspective, should be restrained to aiding future children with extremely low qualities of life (2,Kitcher, 190). He believes that genetic engineering should only be used to avoid disease and illness serving the role of creating a healthier human race. He promotes laissez-faire eugenics, a “hands off” concept that corresponds to three components of eugenic practice, discrimination, coercion and division of traits. It holds the underlying works of genetic testing, accurate information, open access, and freedom of choice. Laissez-faire eugenics promises to enhance reproductive freedom preventing early child death due to genetic disease (3,Kitcher, 198). However there are dangers in Laissez-faire that Kitcher wants to avoid. The first is the historical tendency of population control, eugenics can go from avoiding suffering, to catering to a set of social values that will cause the practice of genetics to become prejudiced, insensitive and superficial. The second is that prenatal testing will become limited to the upper class, leaving the lower class with fewer options, creating biologically driven social barriers. Furthermore the decay of disability support systems due to prenatal testing can lead to an increased pressure to eliminate those unfit for society (4,Kitcher, 214).

In determining the free will of a human’s nature many philosophers want to solve the dilemma of determinism. The dilemma of determinism is as follows (Rowe, p.587):
Society, however, is a state towards which humans have naturally evolved, and our continued existence without society is inconceivable. Thus, although determinism is argued successfully from a causal point of view, it is clearly flawed in a practical context as it fails these fundamental aspects of human life.
Environmental Determinism and Biological Determinism can set restrictions on a person’s behavior. Environmental Determinism is the view that the environment can have a great impact on a person’s behavior. Environmental Determinism is known as the name Climatic Determinism or the name Geographical Determinism. Biological Determinism is the view that a person’s genetic material can set limits on a person’s behavior. Environmental Determinism and Biological Determinism are different because they limit a person’s behavior in different ways and are similar because they have similar effects on different societies.
...criterion that true science is progressive. It has proven able to successfully account for apparent anomalies and generate novel predictions and explanations and therefore has the hallmarks of a currently progressive research program capable of providing us with new knowledge of how the mind works (Ketellar and Ellis 2000). A glance at the Handbook of Evolutionary Psychology (2005), edited by David Buss, shows just how vigorous and productive the field is. Important challenges remain in the discipline, however. The most important are determining the role of domain-specific versus domain-general processes and integrating evolutionary psychology with other behavioral sciences like genetics, neuroscience, and psychometrics (Buss 2004; Rice 2011). Even though critics will remain, Evolutionary Psychology will remain as a scientific discipline for the foreseeable future.
Human intelligence is an eel-like subject: slippery, difficult to grasp, and almost impossible to get straight [3]. Many scientist and psychologist have made numerous attempts to come up with an explanation for the development of human intelligence. For many years, there has been much controversy over what intelligence is and whether it is hereditary or nurtured by the environment. Webster's dictionary defines intelligence as "the ability to acquire and apply knowledge; which includes a sensing an environment and reaching conclusions about the state of that environment [7]. In this paper I am going to examine the factors, which make up ones intelligence. I will be investigating whether or not intelligence is fostered by genetic heritance or nurtured by ones environment.
Evolutionary theory is developed from Darwin’s argument that “suggests that a process of natural selection leads to the survival of the fittest and the development of traits that enable a species to adept to its environment. “ Many have taken this a step further by saying that our genetic inheritance determines not only our physical traits but also certain personality traits and social behaviors. There is such a controversy over significant behaviors that unfold because many believe that we are already pre-programmed human species. It has also been argued that evolution is reflected in functioning and structure of the nervous system and that is has evolutionary factors that have a significant influence on everyday behavior. With what is being said means that if we follow the evolutionary theory, then it would be said that we are already pre-programmed from before birth to follow certain protocols in life. Whether it is from finding a mate or by getting a job. It also believed that this theory gives use cues from our own system to follow, providing us with certain aspects of life from our ancestors. By believing in this theory we can determine that the importance of heredity when influencing human behavior. Behavioral geneticists and evolutionary psychologists have both agreed that not only do genetic factors provide specific behaviors or traits but it also shows the limitations on the emergence of such traits or behaviors. What this means is that our genetics will determine how tall we will be to how ...
When eugenics first began, many scientists began collecting date and research to support the belief and make it one that is sturdier and in order to provide it with more backbone. An example of this research is that studies discovered that a lot of the patients in mental institutions and correction facilities are of relation to one another, so if eugenics is used and takes out this variable it associates itself with a world of less or no crime. Statistics that were created also said that ridding the world of those who are ‘defective’ would save the world a significant amount of money in the future.
New technological advances are being mad every day, especially in genetics. With great innovations comes concerns whether it will have a good cause or be used for bad intentions. One of these is eugenics, the idea to improve genetic composition in humans most specifically in future fetuses. The idea started in 1883 by Sir Francis Galton who wanted to selectively breed humans using desired traits to create a perfect human race. This lead to many unethical moments in history such as the sterilization of unfit humans in the 19th century as well as Hitler’s use of eugenics during WWII. However, current use helps identify possible inherited diseases/conditions in unborn children and remove those traits from the DNA. Although eugenics has been used
Philosophy can be broken down into many different time periods and many different philosophers who each have beliefs on different ideas. A prevalent topic in philosophy is the idea of personal freedoms and the idea of determinism and why and how events take place. There are many different views on determinism; there is the default form determinism, hard determinism, indeterminism, and soft determinism. For determinism, three philosophers who are well know on the subject of determinism are Baron Paul Henri d’Holbach, Robert Kane, and John Stuart Mill’s as they are all different forms of determinist. Baron Paul Henri d’Holbach largely discuss the ideals or default determinism and what specifically makes an event happen. Baron Paul Henri d’Holbach also talks about the ideas of hard determinism. Robert Kane’s man focus is on how determinism differs from indeterminism and who is responsible for events taking place, Kane is also responsible
The belief of eugenics was well-known in the 20th century and the set of its ideals were adopted by many societies across the nation. Eugenics is a study of improving human species by keeping all of the desirable races or breeds. It developed a controversial science regarding to human heredity and personal traits such as positive and negative eugenics. For example, it stated that in order to improve the genetic quality of human race, the society should encourage individuals with superior genes to produce more offspring and discourage reproduction who are considered as socially unfit. These biased eugenics ideas were inspired by Darwin’s theory of natural selection and as well as Galton’s theory of hard heredity. Even in today’s society, people
Height, hair color, eye color and sex are just a few examples of ways our DNA has shaped us. But could it be possible that our DNA also effects the way we behave in society. It is possible that genetics effect us is more ways that we may have imagined. Dr. Peter B. Neubaur believes that shyness, eating disorders, obsessive behavior and psychological illness can all be traced back to our genetics. Sexual orientation is also believed to be derived from genes in our body which determine what sexual preference we prefer. Violence and other types of crimes can be linked back throughout a person’s lineage to witness that other family members have been committed similar crimes without ever meeting one and other.
