But speculative reasonings, which cost so much pains to philosophers, are often formed by the world naturally, and without reflection: As difficulties, which seem unsurmountable in theory, are easily got over in practice. Reason is present and the same in all human actions and at all times; but it does not itself exist in time, and therefore does not enter upon any state in which it did not formerly exist. For of the former alone does she stand in need, in order to preposit the whole series of conditions, and thus present them to the understanding a priorI. But if we once have a completely (and unconditionally) given condition, there is no further necessity, in proceeding with the series, for a conception of reason; for the understanding takes of itself every step downward, from the condition to the conditioned. And this for two reasons; first, because such hypothesis do not advance reason, but rather stop it in its progress; secondly, because this licence would render fruitless all its exertions in its own proper sphere, which is that of experience. I had entertained some hopes, that however deficient our theory of the intellectual world might be, it would be free from those contradictions, and absurdities, which seem to attend every explication, that human reason can give of the material world.
I know there is no mathematician, who will not refuse to be judged by the diagrams he describes upon paper, these being loose draughts, as he will tell us, and serving only to convey with greater facility certain ideas, which are the true foundation of all our reasoning. The same kind of reasoning runs through politics, war, commerce, economy, and indeed mixes itself so entirely in human life, that it is impossible to act or subsist a moment without having recourse to it.
