We perceive nothing by the senses not subject to the laws of organism.
III. Internal sensible representations cannot be formed of other elements than those furnished by sensations.
IV. Whatever is said concerning the pre-existence of sensible representations to organic impressions, besides being said without any reason, is in contradiction with experience.
V. Geometrical ideas, or ideas relating to sensible intuitions, are not innate; since they are the acts of the understanding which operates upon materials provided by the sensibility.
VI. Intuitive ideas of the intellectual order are not innate, because they are nothing else than the acts of the understanding or will, presented to our perception in reflex consciousness.
VII. General determinate ideas are not innate, since they are the representation of intuitions, upon which some act has of necessity been performed.
VIII. There is no ground of affirming that general indeterminate ideas, which seem to be acts of the faculty perceptive of objects under a general reason, are innate.
IX. All that there is of innate in our mind is sensitive and intellectual activity; but both to be put into motion, require objects to affect them.
X. The development of this activity begins with organic affections; and although it goes far beyond the sphere of sensibility, it always remains more or less subject to the conditions imposed by the union of the soul and body.
XI. The intellectual activity has a priori conditions totally independent of sensibility, and applicable to all objects, no matter what impressions may have been their cause. The principle of contradiction figures as the first among these conditions.
XII. There is then in our mind something a priori and absolute, which cannot be altered, even although all the impressions we receive from objects be totally varied, nor if all the relations we have with them were to undergo a radical change.

IDEA OF BEING
CHAPTER I.
IDEA OF BEING
1. There is in our understanding the idea of being. Independent of sensations, and in an order far superior to them, there exist ideas in our understanding, which extend to, and are a necessary element of all thought. The idea of being, or of ens, holds the first rank among these. When the scholastics said that the object of the understanding was being, "objectum intellectus est ens," they enunciated a profound truth, and pointed out one of the most certain and important of all ideological facts.
2. Being, or ens in se, abstracted from all modification and determination, is, considered in its greatest generality, conceived by our understanding. Whatever may be the origin of this idea, or the mode of its formation in our understanding, certain it is that it exists. It is of continual application, and without it it is almost impossible for us to think. The verb to be, expressive of this idea, is found in every language: in every discourse, even in the simplest, we meet this expression: the learned and the ignorant, alike, continually employ it in the same sense, and with equal facility.
The only difference, as to the use of this idea, between the rustic and the philosopher, is, that the one does, the other does not, reflect upon it: but the direct perception is the same in both, equally clear in all cases. Such a thing is or is not; was or was not; will be or will not be; there is something or nothing; we had or did not have; we shall have or shall not have, are all applications of the idea of being, applications made alike by all persons, without the least shadow of obscurity; all comprehend perfectly well the sense of these words, and the mind consequently has the idea corresponding to them. The difficulty, if any there be, begins with the reflex act, in the perception, not of being, but of the idea of being. So far as the direct act is concerned, the conception is so perfectly clear as to leave nothing to be desired.
3. Experience teaches this, but it can also be proved by conclusive arguments. All philosophers agree that the principle of contradiction is evident of itself to all men, that it needs no application, to understand the sense of the words sufficing; which could not be true did not all men have the idea of being. The principle is, that "it is impossible for a thing to be, and not to be at same time." Here, then, is no question of any thing determinate; neither of body nor of mind, of substance nor of accidents, of infinite nor of finite, but of being, of a thing, whatever it may be, in its greatest generality; of which it is affirmed that it cannot both be and not be at the same time. Had we no idea of being, the principle would mean nothing: contradiction is inconceivable when we have no idea of the contradicting extremes, and here the extremes are being and not-being.
4. The same is seen in another principle, closely resembling, if not identical with, that of contradiction: "every thing either is or is not." Here, also, there is question of being in its greatest indeterminateness, considered only as being, as nothing more. Without the idea of being, the axiom could have no meaning.
5. The principle of Descartes, "I think, therefore I am," also includes the idea of being: "I am." When he undertakes to explain it, this philosopher relies upon the fact that what is not, cannot act; thus the idea of being enters not only into the principle of Descartes, but is even the foundation upon which he rests it.
6. Whether we make the inward sense the basis of our cognitions, or prefer the evidence by which one idea is contained in another, it is always necessary to make the idea of being a primary element; we must suppose the understanding to be before it can think; we must suppose thought to be before we can make use of it; we must suppose our sensations and sentiments, the operations and affections of our souls, to be, before we can investigate their causes, their origin, and inquire into their nature; we must suppose ourselves to be, that we are, before we can advance one step in any sense. The idea of being does then exist in our mind, and is an element indispensable to all intellectual acts.
CHAPTER II.
SIMPLICITY AND INDETERMINATENESS OF THE IDEA OF BEING
7. Nothing can be conceived more simple than the idea of being. It cannot be composed of elements. It allows of nothing determinate, since it is in itself absolutely indeterminate. The instant that something determinate is made to enter it, it is in a manner destroyed; it is no longer the idea of being, but of such a being; an idea applied, but not the idea of the being in all its generality.
8. How shall we make it understood what we would express by the word being, or ens? If we say that it comprises all, even the most unlike and opposite things, there is no reason why it may not be understood what it is. To join to the idea of being any determination, is to introduce into it a heterogeneous element, which in no manner belongs to it, and can only accompany it as a pure aggregation, but can never combine with it, without rendering it what it is not. If the idea of subsistence be combined with that of being, we no longer have the pure idea of being, but that of subsistence.
9. The idea of being is then most simple; it cannot be resolved into elements, and cannot consequently spring from speech, unless as from an exciting cause. If we be asked, for example, what we understand by substance, by modification, cause or effect, we explain it by uniting to the idea of being that of subsistence or inherence, that of productive force, or of a thing produced; but it is impossible for us to explain being, otherwise than by itself. We may make use of the words, something, what is, reality, and the like, but all these are inadequate to explain the thing itself; they are but the efforts we make to excite in the understanding of others the idea we contemplate in our own. If we would give further explanations by showing how the idea corresponding to the word being, is
