Determinism means that all events, including thoughts and actions, must necessarily proceed as determined. This is not a matter of choice, but the state and condition of the system. Whatever has been determined to happen must happen, being determined to happen, it inevitably will happen.
And every time you decide to have dinner in a restaurant, the "state and condition of the system" will determine that you must make a choice from the menu. So, being determined to happen, your choosing inevitably will happen.
At some point I hope you will realize that determinism doesn't actually change anything.
Given a deterministic system, if dinner at 8pm is determined, you have dinner at 8pm. Being determined, you cannot not have dinner precisely when it is determined that you have dinner 8pm.
Your mental processes, based on multiple inputs, bring you to the point where you inevitably 'choose' to have dinner at 8pm.
There being no alternative to your choice to have dinner at precisely the determined time, 8pm, and there being no alternative but to have dinner at 8pm , it was never a matter of freedom of choice or freedom of will to 'choose' to have dinner at 8pm. The action was inevitable, fixed, set by the system, a web of causality, as it evolves from prior to current and future states without deviation, output utterly predictable if all the elements are known.
Determinism, in philosophy and science, the thesis that all events in the universe, including human decisions and actions, are causally inevitable. Determinism entails that, in a situation in which a person makes a certain decision or performs a certain action, it is impossible that he or she could have made any other decision or performed any other action. In other words, it is never true that people could have decided or acted otherwise than they actually did.''
That's all I have time for, being Saturday night, it's time to go out for dinner.
