SECT. LII. Secondly, the Ideas of the Mind are Universal, Eternal, and

It is even in the infinite that my mind knows the finite. When we say a man is sick, we mean a man that has no health; and when we call a man weak, we mean one that has no strength. We know sickness, which is a privation of health, no other way but by representing to us health itself as a real good, of which such a man is deprived; and, in like manner, we only know weakness, by representing to us strength as a real advantage, which such a man is not master of. We know darkness, which is nothing real, only by denying, and consequently by conceiving daylight, which is most real, and most positive. In like manner we know the finite only by assigning it a bound, which is a mere negation of a greater extent; and consequently only the privation of the infinite. Now a man could never represent to himself the privation of the infinite, unless he conceived the infinite itself: just as he could not have a notion of sickness, unless he had an idea of health, of which it is only a privation. Now, whence comes that idea of the infinite in us?

Immutable.

Oh! how great is the mind of man! He carries within him wherewithal to astonish, and infinitely to surpass himself: since his ideas are universal, eternal, and immutable. They are universal: for when I say it is impossible to be and not to be; the whole is bigger than a part of it; a line perfectly circular has no straight parts; between two points given the straight line is the shortest; the centre of a perfect circle is equally distant from all the points of the circumference; an equilateral triangle has no obtuse or right angle: all these truths admit of no exception. There never can be any being, line, circle, or triangle, but according to these rules. These axioms are of all times, or to speak more properly, they exist before all time, and will ever remain after any comprehensible duration. Let the universe be turned topsy-turvy, destroyed, and annihilated; and even let there be no mind to reason about beings, lines, circles, and triangles: yet it will ever be equally true in itself, that the same thing cannot at once be and not be; that a perfect circle can have no part of a straight line; that the centre of a perfect circle cannot be nearer one side of the circumference than the other. Men may, indeed, not think actually on these truths: and it might even happen that there should be neither universe nor any mind capable to reflect on these truths: but nevertheless they are still constant and certain in themselves although no mind should be acquainted with them; just as the rays of the sun would not cease being real, although all men should be blind, and no body have eyes to be sensible of their light. By affirming that two and two make four, says St. Augustin, man is not only certain that he speaks truth, but he cannot doubt that such a proposition was ever equally true, and must be so eternally. These ideas we carry within ourselves have no bounds, and cannot admit of any. It cannot be said that what I have affirmed about the centre of perfect circles is true only in relation to a certain number of circles; for that proposition is true, through evident necessity, with respect to all circles ad infinitum. These unbounded ideas can never be changed, altered, impaired, or defaced in us; for they make up the very essence of our reason. Whatever effort a man may make in his own mind, yet it is impossible for him ever to entertain a serious doubt about the truths which those ideas clearly represent to us. For instance, I never can seriously call in question, whether the whole is bigger than one of its parts; or whether the centre of a perfect circle is equally distant from all the points of the circumference. The idea of the infinite is in me like that of numbers, lines, circles, a whole, and a part. The changing our ideas would be, in effect, the annihilating reason itself. Let us judge and make an estimate of our greatness by the immutable infinite stamp within us, and which can never be defaced from our minds. But lest such a real greatness should dazzle and betray us, by flattering our vanity, let us hasten to cast our eyes on our weakness.
