Or to take another example.You want to marry, but your potential wife to be, whom you love deeply, says you must adopt her/his faith. Now if you can do that, then it's certainly your choice. If on the other hand, by doing that you feel guilty and sincerely believe you did the wrong thing and wished you did not believe your faith but believed hers instead for convenience, yet you still believe your faith and not hers even if you do pretend, then again it's not a choice. So I might be wrong, and maybe some peopel can choose what to believe at will. I just have a hard time believing it since everything I have ever believed all my life has never been out of choice.
It is not even my choice to believe that 1+1=2. It's just too logical. As for the floor, it's too palpable. As for God, that's one's bizare. i used to not believe, now I do, And in both cases it was never a matter of choice. When I didn't, I didn't. Now I do, I do. I don't know why, I just do.
