Can we really make conscious decisions, or is agency just a trick of the brain?

We tend to take it for granted that conscious thoughts precede our actions. However, the US scientist Benjamin Libet’s groundbreaking 1980s experiments on the relationship between brain activity, conscious thoughts and physical actions caused some scientists and philosophers to rethink the concept of ‘free will’ and ask whether our decisions are made subconsciously before we’re even aware of them.
