Injustice, poverty, slavery, ignorance - these may be cured by reform or revolution. But men do not live only by fighting evils. They live by positive goals, individual and collective, a vast variety of them, seldom predictable, at times incompatible. Isaiah Berlin
Just as love is an orientation which refers to all objects and is incompatible with the restriction to one object, so is reason a human faculty which must embrace the whole of the world with which man is confronted. Erich Fromm
It is clear to me that people often want incompatible things. They want danger and excitement on the one hand, and safety and security on the other, and often simultaneously. Contradictory desires mean that life can never be wholly satisfying or without frustration. Theodore Dalrymple
A lot of people feel trapped by circumstance, by the expectations of others or the perception that they need a lot of money. They would like to have a different direction in their lives, but they're held back by fear or desires that are incompatible with that freedom. Roz Savage
