One of the main philosophical questions is: Is everything in life predestined or not?
In my view, everything up the smallest detail must be predestined. Here is the explanation for it: If one looks back and views the course of your life you see exactly how it has proceeded second by second. Your life has run a certain path. That is the way it went. What difference does it make at what point in time you look at it looking back or forward? Life will go as it will go. I believe everything is predestined - not only decisions, thoughts, actions but also the growing of a plant, the flow of a river... everything you can think of.
I find nothing concerning this thought in published works of philosophy. Do you know of any works that talk about this?
