I doubt, however, whether our brother Kierkegaard is altogether in the right, for this same abstract thinker, or thinker of abstractions, thinks _in order that_ he may exist, that he may not cease to exist, or thinks perhaps in order to forget that he will have to cease to exist. This is the root of the passion for abstract thought. And possibly Hegel was as infinitely interested as Kierkegaard in his own concrete, individual existence, although the professional decorum of the state-philosopher compelled him to conceal the fact. Faith in immortality is irrational. And, notwithstanding, faith, life, and reason have mutual need of one another. This vital longing is not properly a problem, cannot assume a logical status, cannot be formulated in propositions susceptible of rational discussion; but it announces itself in us as hunger announces itself. Neither can the wolf that throws itself with the fury of hunger upon its prey or with the fury of instinct upon the she-wolf, enunciate its impulse rationally and as a logical problem. Reason and faith are two enemies, neither of which can maintain itself without the other. The irrational demands to be rationalized and reason only can operate on the irrational. They are compelled to seek mutual support and association. But association in struggle, for struggle is a mode of association. In the world of living beings the struggle for life establishes an association, and a very close one, not only between those who unite together in combat against a common foe, but between the combatants themselves. And is there any possible association more intimate than that uniting the animal that eats another and the animal that is eaten, between the devourer and the devoured? And if this is clearly seen in the struggle between individuals, it is still more evident in the struggle between peoples. War has always been the most effective factor of progress, even more than commerce. It is through war that conquerors and conquered learn to know each other and in consequence to love each other.
