Rationality, Reason and Logic

These words form a web of confusion. Personally, I have no desire to be rational. Rationality is a Cartesian idea, in which all knowledge is based upon some kind of analytic schema, pace Quine.
Reason I can deal with - it is logic designed to convince; argument that is both valid and persuasive. Logic alone is not persuasive. An example - 1.crows are black. 2. crows are birds. Thus 3. birds are black. A valid argument; the premises are true. Sadly the conclusion is somewhat wide of the mark. So much for rationalism.
