“Rightness of limitation is essential for growth of reality. Unlimited possibility and abstract creativity can procure nothing. The limitation, and the basis arising from what is already actual, are both of them necessary and interconnected.”

Context: Creativity arises out of the tension between spontaneity and limitations, the latter (like the river banks) forcing the spontaneity into the various forms which are essential to the work of art or poem.

What I Saw in America (1922)
Context: The truth is that prohibitions might have done far less harm as prohibitions, if a vague association had not arisen, on some dark day of human unreason, between prohibition and progress. And it was the progress that did the harm, not the prohibition. Men can enjoy life under considerable limitations, if they can be sure of their limited enjoyments; but under Progressive Puritanism we can never be sure of anything. The curse of it is not limitation; it is unlimited limitation. The evil is not in the restriction; but in the fact that nothing can ever restrict the restriction. The prohibitions are bound to progress point by point; more and more human rights and pleasures must of necessity be taken away; for it is of the nature of this futurism that the latest fad is the faith of the future, and the most fantastic fad inevitably makes the pace. Thus the worst thing in the seventeenth-century aberration was not so much Puritanism as sectarianism. It searched for truth not by synthesis but by subdivision. It not only broke religion into small pieces, but it was bound to choose the smallest piece.

"Introductory" in The Physical Principles of the Quantum Theory (1930) as translated by Carl Eckhart and Frank C. Hoyt, p. 10
Context: Light and matter are both single entities, and the apparent duality arises in the limitations of our language. It is not surprising that our language should be incapable of describing the processes occurring within the atoms, for, as has been remarked, it was invented to describe the experiences of daily life, and these consist only of processes involving exceedingly large numbers of atoms. Furthermore, it is very difficult to modify our language so that it will be able to describe these atomic processes, for words can only describe things of which we can form mental pictures, and this ability, too, is a result of daily experience. Fortunately, mathematics is not subject to this limitation, and it has been possible to invent a mathematical scheme — the quantum theory — which seems entirely adequate for the treatment of atomic processes; for visualisation, however, we must content ourselves with two incomplete analogies — the wave picture and the corpuscular picture.
