Now, of these two ways of knowing truth, which precedes in the chronological order of human knowledge? Is it not certain, may it not be avowed by every one, that the particular precedes the general, that the concrete precedes the abstract, that we begin by perceiving such or such a determinate truth, in such or such a case, at such or such a moment, in such or such a place, before conceiving a general truth, independently of every application and different circumstances of place and time? 2d. We can perceive the same truth without asking ourselves this question: Have we the ability not to admit this truth? We perceive it, then, by virtue alone of the intelligence which has been given us, and which enters spontaneously into exercise; or rather, we try to doubt the truth which we perceive, we attempt to deny it; we are not able to do it, and then it is presented to reflection as superior to all possible negation; it appears to us no longer only as a truth, but as a necessary truth. Is it not also evident, that we do not begin by reflection, that reflection supposes an anterior operation, and that this operation, in order not to be one of reflection, and not to suppose another before it, must be entirely spontaneous; that thus the spontaneous and instinctive intuition of truth precedes its reflection and necessary conception? Reflection is a progress more or less tardy in the individual and in the race. It is, _par excellence_, the philosophic faculty; it sometimes engenders doubt and skepticism, sometimes convictions that, for being rational, are only the more profound. It constructs systems, it creates artificial logic, and all those formulas which we now use by the force of habit as if they were natural to us. But spontaneous intuition is the true logic of nature. It presides over the acquisition of nearly all our cognitions. Children, the people, three-fourths of the human race never pass beyond it, and rest there with boundless security. The question of the origin of human cognitions is thus resolved for us in the simplest manner: it is enough for us to determine that operation of the mind which precedes all others, without which no other would take place, and which is the first exercise, and the first form of our faculty of knowing.[29]
