ity are the essentials; dogmatism, rigidity, prejudice, caprice, arising from routine, passion, and flippancy are fatal.
(b) To decide an issue, the appropriate principles must also be selected (b) This selection of data is, of course, for the sake of controlling the development and elaboration of the suggested meaning in the light of which they are to be interpreted (compare p. 76). An evolution of conceptions thus goes on simultaneously with the determination of the facts; one possible meaning after another is held before the mind, considered in relation to the data to which it is applied, is developed into its more detailed bearings upon the data, is dropped or tentatively accepted and used. We do not approach any problem with a wholly naïve or virgin mind; we approach it with certain acquired habitual modes of understanding, with a certain store of previously evolved meanings, or at least of experiences from which meanings may be educed. If the circumstances are such that a habitual response is called directly into play, there is an immediate grasp of meaning. If the habit is checked, and inhibited from easy application, a possible meaning for the facts in question presents itself. No hard and fast rules decide whether a meaning suggested is the right and proper meaning to follow up. The individual's own good (or bad) judgment is the guide. There is no label on any given idea or principle which says automatically, "Use me in this situation"—as the magic cakes of Alice in Wonderland were inscribed "Eat me." The thinker has to decide, to choose; and there is always a risk, so that the prudent thinker selects warily, subject, that is, to confirmation or frustration by later events. If one is not able to estimate wisely what is relevant to the interpretation of a given perplexing or doubtful issue, it avails
