12. Formal Logic I

We must first realize what a concept is. The fact that people are so little aware of what a concept is is due to the lack of study of logic on the part of the learned. When we encounter an object, the first thing that happens is sensation. We notice a color, a taste or a smell, and this fact, which takes place between man and object, we must first consider as characterized by sensation. What is in the statement: something is warm, cold and so on, is a sensation. But we actually do not have this pure sensation in ordinary life. When we look at a red rose, we not only perceive the red color; when we interact with objects, we always perceive a group of sensations at once. We call the combination of sensations “red, scent, extension, form” a “rose.” We do not actually perceive individual sensations, only groups of sensations. Such a group can be called a “perception”.
