Niels Bohr

To ask questions can become the laziest and wobbliest occupation of a mind, but when you must yourself answer the problem that you have posed, you will meditate your question with care and frame it with precision.

Belief is not restricted to a brief affirmation based on imitation; rather, it has degrees and stages of development. It is like a seed growing into a fully grown, fruit-bearing tree; like the sun's image in a mirror or in a drop of water to its images on the sea's surface and to the sun itself.
