"There is a flair which long practise and 'sympathetic touch' bestow. The trained observer learns how to profit by small indications, as an old seaman discerns, sooner than the landsman, the signs of coming storm." There is, in short, a vast amount of guess work involved, and it is no wonder that scholars, who enjoy precision, so often confine their attentions to the neater formulations of other scholars.]
"The theory of Relativity," says a critic whose eyelids, like the Lady Lisa's, are a little weary, "promises to develop into a principle as adequate to universal application as was the theory of Evolution. This latter theory, from being a technical biological hypothesis, became an inspiring guide to workers in practically every branch of knowledge: manners and customs, morals, religions, philosophies, arts, steam engines, electric tramways—everything had 'evolved.' 'Evolution' became a very general term; it also became imprecise until, in many cases, the original, definite meaning of the word was lost, and the theory it had been evoked to
