““Reason, then, goes to work only after it has been supplied with a suitable set of inputs, or premises. If reason is to be applied to discovering and choosing courses of action, then those inputs include, at the least, a set of should's, or values to be achieved, and a set of is's, or facts about the world in which the action is to be taken. Any attempt to justify these should's and is's by logic will simply lead to a regress to new should's and is's that are similarly postulated.””
