Pedantry and mastery are opposite attitudes toward rules. To apply a rule to the letter, rigidly, unquestioningly, in cases where it fits and in cases where it does not fit, is pedantry. ... To apply a rule with natural ease, with judgment, noticing the cases where it fits, and without ever letting the words of the rule obscure the purpose of the action or the opportunities of the situation, is mastery.

p. 148George Polya
Our assent to the hypothesis implies that it is held to be true of all particular instances. That these cases belong to past or to future times, that they have or have not already occurred, makes no difference in the applicability of the rule to them. Because the rule prevails, it includes all cases.
William Whewell
In the first place, it is not improper to observe, that the law of cases of necessity is not likely to be well furnished with precise rules; necessity creates the law, it supersedes rules; and whatever is reasonable and just in such cases, is likewise legal; it is not to be considered as matter of surprise, therefore, if much instituted rule is not to be found on such subjects.
William Scott Stowell
No man can certainly know, or ought to conclude, concerning himself or others, as long as they live, that the season of grace is quite over with them. As we can conceive no rule God hath set to Himself to proceed by, in ordinary cases of this nature; so nor is there any He hath set unto us to judge by, in this case. It were to no purpose, and could be of no use to men to know so much; therefore it were unreasonable to expect God should have settled and declared any rule, by which they might come to the knowledge of it.
John Howe
There are clear cases in which "understanding" literally applies and clear cases in which it does not apply; and these two sorts of cases are all I need for this argument.
John Searle
The great decisions of human life have as a rule far more to do with the instincts and other mysterious unconscious factors than with conscious will and well-meaning reasonableness. The shoe that fits one person pinches another; there is no recipe for living that suits all cases. Each of us carries his own life-form—an indeterminable form which cannot be superseded by any other.
