and often lie close beside us. Therefore for overcoming sudden dangers, and also for fighting with opponents and enemies, the most essential qualifications are coolness and presence of mind. The former consists in the silence of the will so that the intellect can act; the latter in the undisturbed activity of the intellect under the pressure of events acting on the will; therefore the former is the condition of the latter, and the two are nearly related; they are seldom to be found, and always only in a limited degree. But they are of inestimable advantage, because they permit the use of the intellect just at those times when we stand most in need of it, and therefore confer decided superiority. He who is without them only knows what he should have done or said when the opportunity has passed. It is very appropriately said of him who is violently moved, i.e., whose will is so strongly excited that it destroys the purity of the function of the intellect, he is disarmed; for the correct knowledge of the circumstances and relations is our defence and weapon in the conflict with things and with men. In this sense Balthazar Gracian says: "Es la passion enemiga declarada de la cordura" (Passion is the declared enemy of prudence). If now the intellect were not something completely different from the will, but, as has been hitherto supposed, knowing and willing had the same root, and were equally original functions of an absolutely simple nature, then with the rousing and heightening of the will, in which the emotion consists, the intellect would necessarily also be heightened; but, as we have seen, it is rather hindered and depressed by this; whence the ancients called emotion animi perturbatio. The intellect is really like the reflecting surface of water, but the water itself is like the will, whose disturbance therefore at once destroys the clearness of that mirror and the distinctness of its images. The organism is the will itself, is embodied will, i.e., will objectively perceived in the brain. Therefore many of its functions, such as respiration, circulation, secretion of bile, and muscular power,
