Our character is composed of our ideas and our feelings: and, since it has been proved that we give ourselves neither feelings nor ideas, our character does not depend on us. If it did depend on us, there is nobody who would not be perfect. If one does not reflect, one thinks oneself master of everything; but when one does reflect, one realizes that one is master of nothing
Answer me, you who believe that animals are only machines. Has nature arranged for this animal to have all the machinery of feelings only in order for it not to have any at all?
I also know that we must cultivate our garden. For when man was put in the Garden of Eden, he was put there ut operaretur eum, to work; which proves that man was not born for rest.
