Johann Gottlieb Fichte Quote

The original thinking force of the universe progresses and develops itself in all possible determinations of which it is capable, just as the other original natural forces progress and assume all possible configurations. I am a particular determination of the formative force, like the plant; a particular determination of the peculiar motive force, like the animal; and in addition to this a determination of the thinking force: and the union of these three basic forces into one force, into one harmonious development, is the distinguishing characteristic of my species.
