If determinism exists then there is nothing you can do about it – complaining about it also changes nothing because you were predetermined to complain.
If determinism does not exist, and we do have free will, then congratulations! You are free to choose if you want to believe in determinism or free will!
If compatibilism is true then you are free to choose your greatest desire which was highly influenced by your nature. Either you will choose to believe in determinism or free will because your personal nature dictates it. You have little to no freedom – because you chose something that was strongly influenced by your nature – which you have no control over. Again, you are ‘free’ to a very limited or virtually nonexistent extent to choose your path in life. So you can both complain or support determinism because of a small shred of free will.
If you are confused then welcome to the absurdity of life! The more I read this the less sense it makes to me too! Now got to bed – although this suggestion of mine is only relevant if free will exists, because if determinism is true that you will go to bed at a time when you were predetermined to go to bed, and my commands have no actual influence on your action. Or, if compatibilism is true than you will go to bed when you feel like it though this feeling is largely beyond your own self control, or conscious choosing.
I honesty don’t know why I’m still writing this. Maybe because it was predetermined and I have no control – or I’m just exercising my free will by showing you I can continue to write for as long as I will it to happen.
If you read all this then you are truly a noble knight on the path towards either enlightenment or insanity, perhaps a mix o f both. The latter is always more interesting.
