Eugen Rosenstock-Huessy said this quote

For such is the noble nature of man, that his heart will never wholly lose itself in one single passion or idol, or, as people call it apologetically, one idea. On it goes from one devotion to the next, not because it is ashamed of its first love, but because it must be on fire perpetually. To fall for Reason, as our grandfathers did, is but one Fall of Man among his many passionate attempts to find the apples of knowledge and eternal life, both in one. When a nation, or individual, declines the experiences that present themselves to passionate hearts only, they are automatically turned out from the realm of history. The heart of man either falls in love with somebody or something, or it falls ill. It can never go unoccupied. And the great question for mankind Is what is to be loved or hated next, whenever an old love or fear has lost its hold.
