I could've chosen differently.

我也可能做出不同的选择
So I wasn't determined or predetermined to make that choice.

我并非注定要做那个选择的
So if we were to spell out the argument somewhat more fully,

因此我们要更完整地阐述这个论证的话
it might be, "We have free will,

它应该是人有自由意志
but you can't both have free will

但人不能既有自由意志
and be subject to determinism or subject to deterministic laws."

又遵从决定论或服从确定性的定律
And every physical object, or every purely physical object,

is subject to deterministic laws

都遵从着确定性的定律
because the laws of physics are deterministic.

因为物理定律是确定性的
You put these things together and you get the conclusion that we,

综上所述你就能得到这样的结论
since we've got free will,

由于我们有自由意志
can't be a purely physical object.

所以不可能是纯粹的物理对象
