Does 2+2 really equal 4? What realm of truth am I in when I speak about my pain? What kind of truth claim is it to speak about the existence of "Poland"? How about the existence of ghosts and gods?
Spencer Greenberg breaks down his taxonomy of truth claims to help us better understand what we and others might be saying when we declare something to be true. He also lays out his personal philosophy of Valuism, a deceptively simple yet illuminating framework that can guide your behavior and focus your mind on what really matters to you.
