The Mind or Pure Understanding

The subject of this third treatise is a little dry and sterile. It examines the mind considered in itself and without any relation to the body, in order to recognize the weaknesses that are proper to it and the errors it holds only from itself. The senses and imagination are fruitful and inexhaustible sources of wanderings and illusions; but the mind, acting by itself, is not so subject to error. One had difficulty finishing the two preceding treatises; one has difficulty beginning this one. It is not that one cannot say enough things about the properties of the mind, but it is that one does not seek here so much its properties as its weaknesses. One should not therefore be surprised if this treatise is not so ample, and if it does not discover as many errors as those that preceded it. One should not complain either if it is a little dry, abstract and demanding. One cannot always, in speaking, stir the senses and imagination of others, and even one should not always do so. When a subject is abstract, one can hardly render it sensible without obscuring it; it suffices to render it intelligible. There is nothing so unjust as the ordinary complaints of those who wish to know everything and who wish to apply themselves to nothing. They become angry when one begs them to render themselves attentive; they wish always to be touched, and that one incessantly flatters their senses and passions. But what then? We recognize our powerlessness to satisfy them. Those who write novels and comedies are obliged to please and to render attentive; for us, it is enough if we can instruct even those who make an effort to render themselves attentive.

The Limitations of the Mind — Its Consequences

The mind, being limited, cannot comprehend what pertains to the infinite

What is found first, therefore, in the thought of man is that it is very limited; from which one can draw two very important consequences: the first, that the soul cannot perfectly know the infinite; the second, that it cannot even distinctly know several things at once. For just as a piece of wax is not capable of having at the same time an infinity of different figures, so the soul is not capable of having at the same time the knowledge of an infinity of objects: and just as a piece of wax cannot be square and round in the same sense, but only half square and half round, and that the more different figures it has the less perfect and less distinct they will be; so the soul cannot perceive several things at once, and its thoughts are all the more confused as they are more numerous.

Philosophers scatter their mental powers by addressing subjects that involve too many relationships and depend on too many factors, while following no order in their studies

Men fall into a vast number of errors not only because they occupy themselves with questions that border on the infinite—for their minds are not infinite—but also because they tackle subjects of immense scope, while their understanding is very limited.

The mind cannot apply itself for long to objects that have no relation to it, or that do not partake in some way of the infinite

The human mind is prone to error not only because it is not infinite, or because its scope is narrower than the objects it considers—as we have explained in the two preceding chapters—but also because it is unstable, lacks firmness in its activity, and cannot keep its attention fixed steadily upon a subject long enough to examine it fully.
