SOCRATES
According to Socrates, “no one commits an evil act knowingly and doing wrong arises out of ignorance.” A person will commit only moral evil if he lacks moral knowledge. Sometimes, a person may have knowledge but he deliberately commits an evil act to satisfy his hidden motive. -

PLATO
Plato held that moral values are objective in the sense that they exist in a spirit-like realm beyond subjective human conventions. He held that they are absolute, or eternal, in that they never change, and also that they are universal insofar as they apply to all rational creatures around the world and throughout time. -

ARISTOTLE
The ethics of Aristotle is concerned with action, not as being right in itself irrespective of any other consideration, but with actions conducive to man’s good. Aristotle’s “The Golden Mean Principle” states that to be happy, live a life of moderation. In everything that we do, we must avoid extremes.
