Free Will

Definitions

Determinism is the view that every event is determined by some other event, including our deliberations and actions.

Libertarianism is the view that if we have free will, then we must be able to act differently than we did.

Compatibilism is the view that if the following statement is true, then we have free will:

If we had deliberated differently, we would have acted differently.

On this view, we can have free will regardless of the fact that we could not have deliberated differently.

What kinds of evidence should we consider when we are trying to determine whether we have free will? Should we consider our personal experiences? Neuroscience? The consequences of determinism?
What are the implications of the discussion of free will for society? What are the implications for personal responsibility, morality, and the legal system?
What is causation? In other words, what do we mean when we say that one event causes another event?
Is it possible for an individual to have true free will in a society where social and cultural influences shape our choices?
There are several different sciences aimed at explaining why we, as humans, behave the way we do. What do the findings of these sciences mean for our free will?
Do other animals have free will? Can we ever make a computer that has free will?
How does the notion of determinism differ from the notion of fate?
How does the definition of compatibilism offered above differ from the definition Hank Green offers in the video? Are there instances where this definition is true, but Hank’s definition is not? Are there instances where Hank’s definition is true, but this definition is not?

Philosophically, we would ask whether the two definitions have extensional equality.

Another way of putting this is to ask whether they have the same reference class.
