In the FF forum and Facebook page, every once in a while someone oblivious to the standard definition butts in with the assumption that freethinking means setting the mind completely free – unrestrained even by reason, logic, or reality.

There are three truths which must be accepted at the beginning of any investigation into the problem of knowledge and truth:
The First Fact: The fact of our existence. "I exist."
The First Principle: The principle of contradiction. "A thing can not be and not-be at the same time in the same respect."
The First Condition: The essential capability of the mind to know truth. "My intellect can reason and discover truth."
