Lotze Quotes:
1. To do good to others and increase the sum of general happiness is the one task the fulfilment of which comprises all his moral obligation.
2. For all the laws of this mechanism are but the very will of the universal soul, nothing else than the condition for the realization of God.
3. …how advantageous for the heart the simultaneous overview of huge spaces is; what a pleasure the ability to review a multiplicity of different objects in their reciprocal positions, as if embedded in a secure mesh of relations, is.
4. Every person, every generation poses questions not just to the being in its reality in itself, but in connection with the sense and value, in which the being confronts them through life and history.
5. The constant whetting of the knife is tedious if it is not proposed to cut anything with it.
6. Without a light-sensing eye, and a sound-sensing ear, the whole world would be dark and silent. There would be in it just as little light or sound as there could be toothache without the pain-feeling nerve of the tooth.
7. All the processes in nature are only understandable through the continuant involvement of God; only this involvement arranges the transition of the interaction between different parts of the world.
