“For a Westerner, it is usually sufficient for a proposition to be logically sound. For a Chinese it is not sufficient that a proposition be logically correct, but it must be at the same time in accord with human nature.”

“Reason is the power or capacity whereby we see or detect logical relationships among propositions.”

“The core of science is not controlled experiment or mathetical modeling; it is intellectual honesty. It is time we acknowledge a basic feature of human discourse: when considering the truth of a proposition, one is either engaged in an honest appraisal of the evidence and logical arguments, or one isn't.”

“We rely on faith only in the context of claims for which there is no sufficient sensory or logical evidence.”

“It is wrong for a man to say that he is certain of the objective truth of any proposition unless he can produce evidence which logically justifies that certainty.”

“Believing a given proposition is a matter of believing that it faithfully represents some state of the world, and this fact yields some immediate insights into the standards by which our beliefs should function. In particular, it reveals why we cannot help but value evidence and demand that propositions about the world logically cohere.”
