Expansion of Understanding Quotes

What had been (at the beginning) no bigger than a full stop had expanded into a comma, a word, a sentence, a paragraph, a chapter; now it was bursting into more complex developments, becoming, one might say, a book - perhaps an encylopaedia - even a whole language.

Through learning we grow, becoming more than we were before, and in that sense learning is unselfish, because it results in the transformation of what we were before, a setting aside of the old self in favor of a more complex one.

The standard theory may survive as a part of the ultimate theory, or it may turn out to be fundamentally wrong. In either case, it will have been an important way-station, and the next theory will have to be better.

Sciences usually advances by a succession of small steps, through a fog in which even the most keen-sighted explorer can seldom see more than a few paces ahead. Occasionally the fog lifts, an eminence is gained, and a wider stretch of territory can be surveyed-sometimes with startling results. A whole science may then seem to undergo a kaleidoscopic rearrangement, fragments of knowledge sometimes being found to fit together in a hitherto unsuspected manner. Sometimes the shock of readjustment may spread to other sciences; sometimes it may divert the whole current of human thought.

The earlier truths are not expelled but absorbed, not contradicted but extended; and the history of each science, which may thus appear like a succession of revolutions, is, in reality, a series of developements.

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.

There are many virtues in books, but the essential value is the adding of knowledge to our stock by the record of new facts, and, better, by the record of intuitions which distribute facts, and are the formulas which supersede all histories.

It is given to few to add the store of knowledge, to strike new springs of thought, or to shape new forms of beauty. But so sure as it is that men live not by bread, but by ideas, so sure is it that the future of the world lies in the hands of those who are able to carry the interpretation of nature a step further than their predecessors.
