A Covenant not to defend myself from force, by force, is always void. For... no man can transfer or lay down his Right to save himself from Death.

By this we may understand, there be two sorts of knowledge, whereof the one is nothing else but sense, or knowledge original (as I have said at the beginning of the second chapter), and remembrance of the same; the other is called science or knowledge of the truth of propositions, and how things are called, and is derived from understanding.
