The little word _my_ is the most important one in all human affairs, and properly to reckon with it is the beginning of wisdom. It has the same force whether it is _my_ dinner, _my_ dog, and _my_ house, or _my_ faith, _my_ country, and _my God_. We not only resent the imputation that our watch is wrong, or our car shabby, but that our conception of the canals of Mars, of the pronunciation of "Epictetus", of the medicinal value of salicine, or the date of Sargon I, are subject to revision. Philosophers, scholars, and men of science exhibit a common sensitiveness in all decisions in which their _amour propre_ is involved. Thousands of argumentative works have been written to vent a grudge. However stately their reasoning, it may be nothing but rationalizing, stimulated by the most commonplace of all motives. A history of philosophy and theology could be written in terms of grouches, wounded pride, and aversions, and it would be far more instructive than the usual treatments of these themes. Sometimes, under Providence, the lowly impulse of resentment leads to great achievements. Milton wrote his treatise on divorce as a result of his troubles with his seventeen-year-old wife, and when he was accused of being the leading spirit in a new sect, the Divorcers, he wrote his noble _Areopagitica_ to prove his right to say what he thought fit, and incidentally to establish the advantage of a free press in the promotion of Truth. All mankind, high and low, thinks in all the ways which have been described. The reverie goes on all the time not only in the mind of the mill hand and the Broadway flapper, but equally in weighty judges and godly bishops. It has gone on in all the philosophers, scientists, poets, and theologians that have ever lived. Aristotle's most abstruse speculations were doubtless tempered by highly irrelevant reflections. He is reported to have had very thin legs and small eyes, for which he doubtless had to find excuses, and he was wont to indulge in very conspicuous dress and rings and was accustomed to arrange his hair carefully.[4] Diogenes the Cynic exhibited the impudence of a touchy soul. His tub was his distinction. Tennyson in beginning his "Maud" could not forget his chagrin over losing his patrimony years before as the result of an unhappy investment in the Patent Decorative Carving Company. These facts are not recalled here as a gratuitous disparagement of the truly great, but to insure a full realization of the tremendous competition which all really exacting thought has to face, even in the minds of the most highly endowed mortals.
