The master said, learning without thought is naught; thought without learning is dangerous

He who would learn to fly one day must first learn to stand and walk and run and climb and dance; one cannot fly into flying.

Learning without reflection is a waste. Reflection without learning is dangerous.

A little learning, indeed, may be a dangerous thing, but the want of learning is a calamity to any people.

Learning without thought is labor lost; thought without learning is perilous.

Learning is an ornament in prosperity, a refuge in adversity, and a provision in old age.
