In order to comprehend the notion of Malebranche, such as he held it while he retained his faculties, we must admit nothing that we do not clearly conceive, and reject what we do not understand. Attempting to explain an obscurity by obscurities, is to act like an idiot.
I feel decidedly that my first ideas and my sensations have come to me without any co-operation or volition on my part. I clearly see that I cannot give myself a single idea. I cannot give myself anything. I have received everything. The objects which surround me cannot, of themselves, give me either idea or sensation; for how is it possible for a little particle of matter to possess the faculty of producing a thought?
I am therefore irresistibly led to conclude that the Eternal Being, who bestows everything, gives me my ideas, in whatever manner this may be done. But what is an idea, what is a sensation, a volition, etc.? It is myself perceiving, myself feeling, myself willing.
We see, in short, that what is called an idea is no more a real being than there is a real being called motion, although there are bodies moved. In the same manner there is not any particular being called memory, imagination, judgment; but we ourselves remember, imagine, and judge.
The truth of all this, it must be allowed, is sufficiently plain and trite; but it is necessary to repeat and inculcate such truth, as the opposite errors are more trite still.
Laws of Nature.
How, let us now ask, would the Eternal Being, who formed all, produce all those various modes or qualities which we perceive in organized bodies?
Did He introduce two beings in a grain of wheat, one of which should produce germination in the other? Did He introduce two beings in the composition of a stag, one of which should produce swiftness in the other? Certainly not. All that we know on the subject is that the grain is endowed with the faculty of vegetating, and the stag with that of speed.
There is evidently a grand mathematical principle directing all nature, and affecting everything produced. The flying of birds, the swimming of fishes, the walking or running of quadrupeds, are visible effects of known laws of motion. "Mens agitat molem." Can the sensations and ideas of those animals, then, be anything more than the admirable effects or mathematical laws more refined and less obvious?
