Even mistakes would be considered predestined. For instance, mistakes are made due to lack of attention. If a person is too tired to pay attention to what they are doing then another individuals choice or your own choice has put you in that state of mind. Again, you would be predestined to make the mistake because you were predestined to be in the state of mind to make the mistake.
I disagree. Predestined mistakes? No. Our mistakes are not foreordained, predetermined, or anything of the like. I wrote the following in another thread as it relates to the concept of freewill:
We are driven by our desires. We will always act according to our strongest desire. Many factors influence us, whether they be internal or external. We are somewhat bound, yet we are likewise able to manipulate our desires through knowledge and understanding.
Our destiny is not set in stone in other words. The more we learn and the more we come to understand how life works, the more we leave ignorance behind, thus potentially changing our destiny. Life is a great teacher. Through life we are able to learn wisdom.
With wisdom comes better informed decisions. Soon our old thoughtless choices are changed into informed choices, but not before our desires have been manipulated through education.
We are neither free nor bound. I think we are forever growing into better informed people. I suppose one could argue that growth is inevitable for the aware. I suppose one could effectively argue against free will. However, no matter the reality, we are at least free enough to make mistakes.
