12. Formal Logic I

If people really think logically, in the strict logical sense, they do something other than perceive externally and then visualize what they have perceived; this is only an idea. In logical thinking, however, every thought must be constructed inwardly, it must be created similarly to what I have just explained using the example of the circle. Only then does man approach external reality with this inner mental image and find harmony between the inner picture and external reality. The representation is connected with external perception, the concept has been created by inner construction. Men who really thought logically have always constructed inwardly in this way. Thus Kepler, when he formulated his laws, constructed them inwardly, and then found them in harmony with external reality.
