Tautologies Must Not Be Dismissed
Orthodox philosophic thinking goes like this, “Tautologies are merely true by definition and cannot teach us anything about the world.”

I couldn’t disagree more strongly with this line of reasoning. Not only is it mistaken to dismiss tautologies, it’s completely backwards. For three distinct reasons, tautologies are foundational for critical reasoning; they are the building blocks for an accurate worldview.
