4B: Determinism Flashcards
What is determinism?
The idea that all actions are determined by causes and laws outside our control
What is hard determinism?
The view which denies that humanity has free will and states that all actions have a prior cause. It removes moral responsibility from actions
What is soft determinism?
The view which states we can be both determined and free, as some of our moral choices are free but aspects of our nature are determined
What is another name for soft determinism?
compatibilism
What did John Locke believe?
- because everything that happens is the result of a cause that came before it, everything that happens is determined to happen in a certain way
- Because the world will is like a big cause-and-effect machine, there’s no way of changing what’s going to happen in the future and we have no free will: “Free will is just an illusion”
- There is an unbreakable chain of past causes going back to the beginning of time
John Locke’s locked room analogy
- He asked his readers to imagine a man in a locked room who does not know that it’s locked
- The man thinks he can leave at any time, but in fact cannot
How does Locke’s locked room analogy relate to determinism?
We think we are free to do what we want, but really this is only an illusion and we are determined to do certain things
What is scientific determinism?
the idea that all events in the universe are caused, and in principle, predictable
Which scientist is most influential on hard determinism?
Charles Darwin
What does scientific determinism suggest?
randomness is not intrinsic: just a reflection of our lack of information
What did Newton mean by the universe being a ‘closed system’?
Energy is conserved and finite. Nothing can come into the universe from outside, to make up for energy spent in other forms
What do Newton’s laws suggest?
We live in a mechanical, clockwork universe: everything is determined by physical forces, and these forces can be predicted and known
What discovery did Quantum Physics make?
It is impossible to know both where a particle is, and where it is going. It can be anywhere, there are only probabilities.
What does the Human Genome Project suggest?
- our DNA can code for our physical appearance, intelligence, and even behaviour
- This means it could be that we are all determined to act in certain ways by our genes
What did Daniel Dennett mean by ‘genetic fixity’?
the genes of parents inevitably determine the characteristics of their children
Quote from Nusslein-Volhard
“in the fertilised egg, the genetic program is complete”
- implies a moral agent’s programmed life is decided at conception
What foundings by the Human Genome Project support genetic fixity?
- Addiction: multiple genes can add up to make a moral agent susceptible to addiction. Eg a particular gene can make one moral agent feel sick to a particular stimulus but another moral agent to feel happy to the same stimuli, making it harder for the latter moral agent to give up the stimuli; thus, increasing their risk of addiction. Therefore, whether a moral agent is an addict could purely be determined by a series of genetics.
- Homosexuality: A recent study carried out by Doctor Tuck Ngun on 47 pairs of identical twins found that nine small regions of the human genetic code played a key role in deciding whether a moral agent is heterosexual or homosexual. So confident with their findings, Ngun’s team predicted it was possible to carry out a DNA test on a baby to predict their sexual orientation with 70% accuracy.
Stephen Mobley case
- He murdered a Domino’s pizza store manager and tried to avoid execution by claiming the murder was a result of a mutation in a specific gene
- The judge turned down the appeal, saying the law was not ready to accept such evidence
Abdelmalek Bayout case
- He murdered a man who he claimed insulted him
- He was found guilty, but his sentence was reduced by a year as it was illustrated that he had the mutated MAOA gene
- The judge accepted that Bayout had had no control over his violent actions
What is the MAOA gene?
a gene which is a determining cause of violence
What is Locke’s ‘nurture’ idea?
We are a ‘blank slate’ on which our environment writes our personality
How did Darwin describe natural selection in ‘Origin of Species’?
- The way which creatures are challenged by their environment, and only the fittest or best adapted creatures survive - so only their characteristics get passed on
- Even though genes had not yet been discovered, Darwin realised that the characteristics creatures had were inherited, and could be explained by this long process of evolutionary adaptation and change. Who we are, is the product of evolution.
