The practical man avoids error by refusing to think at all. His method at least cannot be right. It is not right even for the practical uses he prefers exclusively to all others. You see him stumbling into some pit because he refuses to walk with a light and then accusing adverse circumstances or his evil fortune, or he shouts, elbows, jostles, tumbles and stumbles himself into a final success and departs at last, satisfied; leaving behind a name in history and a legacy of falsehood, evil and suffering to unborn generations. The method of the practical man is the shortest and most facile, but the least admirable of all.
Truth is an infinitely complex reality and he has the best chance of arriving nearest to it who most recognises but is not daunted by its infinite complexity. We must look at the whole thought-tangle, fact, emotion, idea, truth beyond idea, conclusion, contradiction, modification, ideal, practice, possibility, impossibility (which must be yet attempted,) and keeping the soul calm and the eye clear in this mighty flux and gurge of the world, seek everywhere for some word of harmony, not forgetting immediate in ultimate truth, nor ultimate in immediate, but giving each its due place and portion in the Infinite Purpose. Some minds, like Plato, like Vivekananda, feel more than others this mighty complexity and give voice to it. They pour out thought in torrents or in rich and majestic streams. They are not logically careful of consistency, they cannot build up any coherent, yet comprehensive systems, but they quicken men’s minds and liberate them from religious, philosophic and scientific dogma and tradition. They leave the world not surer, but freer than when they entered it.
Some men seek to find the truth by imaginative perception. It is a good instrument like logic, but like logic it breaks down before it reaches the goal. Neither ought to be allowed to do more than take us some way and then leave us. Others think that a fine judgment can arrive at the true balance. It does, for a time; but the next generation upsets that fine balancing, consenting to a coarser test or demanding a finer. The religious prefer inspiration, but inspiration is like the lightning, brilliantly illuminating only a given reach of country and leaving the rest in darkness intensified by the sharpness of that light. Vast is our error if we mistake that bit of country for the whole universe. Is there then no instrument of knowledge that can give us the heart of truth and provide us with the key word of existence? I think there is, but the evolution of mankind at large yet falls far short of it; their highest tread only on the border of that illumination. After all pure intellect carries us very high. But neither the scorner of pure intellectual ideation, nor its devotee can attain to the knowledge in which not only the mind thinks about things, but the ideal faculty directly knows them.
