People who know me know that I like Aristotle’s definition of truth. It is a simple definition and it lays out parameters for understanding the reality of what is said:
To say that what is is not, or that what is not is, is false; but to say that what is is, and what is not is not, is true; and therefore also he who says that a thing is or is not will say either what is true or what is false. (Metaphysics 1011b.20–39)
Aristotle, Aristotle in 23 Volumes, Vols.17, 18, Translated by Hugh Tredennick. (Medford, MA: Cambridge, MA, Harvard University Press; London, William Heinemann Ltd., 1933, 1989).
So, when we speak, what we say either corresponds to reality or it does not. Unfortunately, society today does not seem to care for discovering what corresponds with reality. Rather many people prefer an interpretation of events that justifies themselves and puts those they agree with in a bad light. The result of this mindset is the fact that people will only listen to what makes them comfortable and seek to reject what makes them uncomfortable. But if what makes them comfortable is false, then their sources are harmful in seeking out the truth and living in accordance with it.
