In regard to the principle of movement, three philosophies are possible.
1. Elliptic philosophy. Starting-point and stopping-point are not even ideal. Movement of nature recedes from no point, advances towards no point, has no definite tendency, but only flits from position to position.
2. Parabolic philosophy. Reason or nature develops itself according to one universal formula; but the point toward which that development tends is the very same nothingness from which it advances.
3. Hyperbolic philosophy. Reason marches from premisses to conclusion; nature has ideal end different from its origin.
