An idea is a putting truth in check-mate.
He [the "specialist"] is one who, out of all that has to be known in order to be a man of judgment, is only acquainted with one science, and even of that one only knows the small corner in which he is an active investigator. He even proclaims it as a virtue that he takes no cognisance of what lies outside the narrow territory specially cultivated by himself, and gives the name of "dilettantism" to any curiosity for the general scheme of knowledge.
Beliefs constitute the basic stratum, that which lies deepest, in the architecture of our life. By them we live, and by the same token we rarely think of them.... One may symbolize the individual life as a bank of issue. The bank lives on the credit of a gold reserve which is rarely seen, which lies at the bottom of metal coffers hidden in the vaults of the building. The most elementary caution will suggest that from time to time the effective condition of these guaranties--of these credences, one might say, that are the basis of credit--be passed in review.
