Socrates' fundamental principles from Plato's Crito
P1: We must always act on the basis of good reasons and good reasoning, not out of fear, mere self-interest.
P1(a): We value the opinions of
those who know, not the many
P1(b): The principles on which we rely must stand the tests of time and change of circumstances, and the conclusions we draw from them must be ones which we can be constantly faithful.
P2:
It is not enough to live; we must live well, nobly and justly.
P3: We must never do wrong willingly, even in requital.
P4: We must always keep our agreements, provided they are just.
