Key Arguments

• He says that his errors, which alone testify to his imperfection, "depend on the concurrence of two causes, viz, the faculty of cognition, which I possess, and that of election or the power of free choice,—in other words, the understanding and the will."
• By the understanding alone, he "merely apprehend[s] (percipio) the ideas regarding which I may form a judgment; nor is any error, properly so called, found in it thus accurately taken."
• Even though there are innumerable objects of which he has no ideas, this does not mean he is deprived of them as something due; it simply reflects the limited extent of the understanding, and there is no ground to claim that God ought to have endowed him with a larger cognitive faculty.
• In contrast, he cannot complain about his will, since he is conscious of a will "so ample and extended as to be superior to all limits."
• He stresses that among his properties, only the will is such that he cannot clearly conceive it greater in kind; whereas every other finite faculty suggests the idea of a more ample, even infinite analogue in God.

It further occurs to me that we must not consider only one creature apart from the others, if we wish to determine the perfection of the works of Deity, but generally all his creatures together; for the same object that might perhaps, with some show of reason, be deemed highly imperfect if it were alone in the world, may for all that be the most perfect possible, considered as forming part of the whole universe: and although, as it was my purpose to doubt of everything, I only as yet know with certainty my own existence and that of God, nevertheless, after having remarked the infinite power of Deity, I cannot deny that we may have produced many other objects, or at least that he is able to produce them, so that I may occupy a place in the relation of a part to the great whole of his creatures. Whereupon, regarding myself more closely, and considering what my errors are (which alone testify to the existence of imperfection in me), I observe that these depend on the concurrence of two causes, viz, the faculty of cognition, which I possess, and that of election or the power of free choice,—in other words, the understanding and the will. For by the understanding alone, I [neither affirm nor deny anything but] merely apprehend (percipio) the ideas regarding which I may form a judgment; nor is any error, properly so called, found in it thus accurately taken.

And although there are perhaps innumerable objects in the world of which I have no idea in my understanding, it cannot, on that account be said that I am deprived of those ideas [as of something that is due to my nature], but simply that I do not possess them, because, in truth, there is no ground to prove that Deity ought to have endowed me with a larger faculty of cognition than he has actually bestowed upon me; and however skillful a workman I suppose him to be, I have no reason, on that account, to think that it was obligatory on him to give to each of his works all the perfections he is able to bestow upon some.

Nor, moreover, can I complain that God has not given me freedom of choice, or a will sufficiently ample and perfect, since, in truth, I am conscious of will so ample and extended as to be superior to all limits.

And what appears to me here to be highly remarkable is that, of all the other properties I possess, there is none so great and perfect as that I do not clearly discern it could be still greater and more perfect.
