If the art of gardening is at last to turn back from her extravagances and rest with her other sisters, it is, above everything, necessary to have clearly before you what you require . . . It is certainly tasteless and inconsistent to desire to encompass the world with a garden-wall, but very practicable and reasonable to make a garden . . . into a characteristic whole to the eye, heart, and nderstanding alike.
Friedrich SchillerThe reason for you complaint lies, it seems to me, in the constraint which your intellect imposes upon your imagination. Here I will make an observation, and illustrate it by an allegory. Apparently, it is not good-and indeed it hinders the creative work of the mind-if the if the intellect examines too closely the ideas pouring in, as it were, at the gates.
Friedrich Schiller
