Whatever free will is, this can't be the definition of it. Consider two computers, build for one and only one purpose: to compute the first 10 digits of pi. They do this without any external input. But one computer is made of vacuum tubes, one made of transistors, both of which computed the first 10 digits of pi.

They both took the same action (computing the first 10 digits of pi) and it was independent of how they were constructed, and absent any external stimulus. Yet they don't have free will.

Its harder than it looks to define free will; I'd encourage you to try again.
