Gardener and Garden

Out of damp and gloomy days, out of solitutde, out of loveless words directed at us, conclusions grow up in us like fungus: one morning they are there, we know not how, and they gaze upon us, morose and grey. Woe to the thinker who is not the gardener but only the soil of the plants that grow in him!

Nietzsche, Daybreak, IV:382.
