Man is a rational animal. So at least we have been told. Throughout a long life I have searched diligently for evidence in favor of this statement. So far, I have not had the good fortune to come across it.

[Messrs Ogden and Richards] will reply that they are considering the meaning of a "thought," not of a word. A "thought" is not a social phenomenon, like speech, and therefore does not have the two sides, active and passive, which can be distinguished in speech. I should urge, however, that all the reasons which led our authors to avoid introducing images in explaining meaning should have also led them to avoid introducing "thoughts." If a theory of meaning is to be fitted into natural science as they desire, it is necessary to define the meaning of words without introducing anything "mental" in the sense in which what is "mental" is not subject to the laws of physics. Therefore, for the same reasons for which I now hold that the meaning of words should be explained without introducing images – which I argued to be possible in the above-quoted passage – I also hold that meaning in general should be treated without introducing "thoughts," and should be regarded as a property of words considered as physical phenomena. Let us therefore amend their theory. They say: "'I am thinking of A' is the same thing as 'My thought is being caused by A.'" Let us substitute: "'I am speaking of A' is the same thing as 'My speech is being caused by A.'" Can this theory be true?

A man is rational in proportion as his intelligence informs and controls his desires.

How pleasant a world would be in which no man was allowed to operate on the Stock Exchange unless he could pass and examination in economics and Greek poetry, and in which politicians were obliged to have a competent knowledge of history and modern novels.
