let's put the memes aside
I study biochemistry and I was leaning towards materialism as a philosophical view, the more I engage with my course, the more it makes sense to me that all we can see, all we're aware of, boils down to molecules, or even further positive/negative charge interactions of atoms.
I like to define free will as an ability to make a choice without any bias or influence, external, internal, physiological, psychological, whatever, you name it.
It already sounds like an impossible thing, and that's because it is.
Your genes and environment have set a path for you to follow. Even further, one could argue, that the particles that you're made out of are also following a predetermined path, electron transfers, neural connections, carbon cycles, metabolic cycles, etc.
Randomness is a subjective term, it seems that someone unaware of a pattern of which a thing can occur, will call it random.
In my opinion nothing is exactly random, as external forces are always affecting everything, even on a pico-scale so as cheesy as it is
>"there's a reason behind everything"
Also, lack of free will doesn't imply a murderer shouldn't be restricted of freedom, as he himself is a danger to freedom of others
is it his fault?
should he be locked up
