Do People Have Free Will? We don't have "free" will, and that's easy to prove. You do what you like, right? You reject what you don't like, right? And you do everything dependant on your likes and dislikes. Sounds free, right?
The problem is, you don't choose your likes and dislikes, you just have them and devote your life to appeasing them. Where do they come from? Your genetic/biological predispositions set against your environment, which refers to education, experience, parental influences, needs, etc.
All that manifests as will. So free will is like saying free predispositions, or free conditioning. An oxymoron.
But that changes nothing. We learn. We know what is expected of us. We can change our feelings/ likes and dislikes through learning. We have language that allows us to understand complex concepts. Thus, unless you're mentally disabled by damage or disease etc, you are responsible for your actions. No free will required, just the ability to understand.
