Socrates believed that he had a mission socrates critical thinking questions seek after wisdom. He died being faithful to that mission.
He attempted to find a stable and certain truth and a wisdom that would serve as a guide for life. The unexamined life is not worth living! The best manner to examinee that life is through reasoning which employs the dialectical method of inquiry. Plato inherits this belief, expands upon it and promulgates this belief. The Socratic legacy is in turning critical thought quite directly in the direction of humanity, human morality and virtue and the idea of a good life for a human. For Socrates the key to a virtuous life was knowledge of the GOOD and this links ethics with epistemology.
If one knew the Good one would choose it. One always chooses the best of the options available. Socrates believed that no one does wrong voluntarily. Evil is the result of ignorance.
If people knew what was the right thing to do they would do it. We always choose what we think is the best or good for us. Socrates held that people know that OTHER PEOPLE think that it is wrong but they do not totally agree. The wrong doers think that there is something good in doing the evil act even if it is only good for them. If the wrong doers understood why the act was considered to be wrong they would not do it. They do it because they mistake the evil act for a good act in some way. Given options humans will choose the options that appears to be good for them.
Socrates theory does NOT claim that people who do wrong do not know that the act is wrong. Socrates theory does NOT claim that people who do wrong do think that it is correct or right to do. The theory is that people who do wrong know that OTHER PEOPLE think that it is wrong but that the wrong doer does not accept that and does not agree because the wrong doer sees some benefit or good result for the wrong doer. As long as the wrong doer continues to see some benefit or good result for the wrong doer then the wrong doer will continue to do the act that is considered wrong by OTHER PEOPLE. When the wrong doer comes to understand and to know why the OTHER PEOPLE think of the act as being wrong and the wrong doer accepts that then the wrong doer will stop doing that act. Person P knows that OTHER PEOPLE think that act X is WRONG or BAD or EVIL.
