One who is too wise an observer of the business of others, like one who is too curious in observing the labor of bees, will often be stung for his curiosity.

Minds are like parachutes – they only function when open.

Perplexity is the beginning of knowledge.

We shall not cease from exploration. And the end of all our exploring will be to arrive where we started and know the place for the first time.

What we have to do is to be forever curiously testing new opinions and courting new impressions.

Seize the moment of excited curiosity on any subject to solve your doubts; for if you let it pass, the desire may never return, and you may remain in ignorance.

Curiosity killed the cat, but for a while I was a suspect.

Only the curious will learn and only the resolute overcome the obstacles to learning. The quest quotient has always excited me more than the intelligence quotient.

The decay of inquiry stems from some belief that suppresses curiosity.
