“Already determined dawn began to lay

In place across a cloud the slender ray

For prying beneath and *forcing* the lids of sight,

And loosing the pent-up music of overnight.”

—Robert Frost (1874–1963)

“It is quite true, as some poets said, that the God who created man must have had a sinister sense of humor, creating him a reasonable being, yet *forcing* him to take this ridiculous posture, and driving him with blind craving for this ridiculous performance.”

—D.H. (David Herbert)

“An empty head is not really empty; it is stuffed with rubbish. Hence the difficulty of *forcing* anything into an empty head.”

—Eric Hoffer (1902–1983)
