Do you believe in free will?

[The Magic Pudding]

If we are composed of nothing other than matter then doesn't that mean all that we are as humans is a bunch of chemicals and particles being governed by physical laws?

Ye those laws are always at play.
Comforting isn't it?

Do we have no more control over ourselves then a rock does when falling down a hill, or a computer governed completely by our programming?

I don't entirely understand rockness, parts of me was once was rock but I've lost touch. It's my impression rocks just go with the flow, I don't know where this impression comes from.

It seems like that is the only option if materialism is true, however it just doesn't seem like that explanation fits in with the universal experience of free will. I mean if an object is dropped it must necessarily fall to the ground because of gravity. But there is no physical law that makes it necessary for me to post on this forum, it seems like I freely chose to do it myself.

It seems your sense is leaking through your seams.
