One can't understand everything at once, we can't begin with perfection all at once! In order to reach perfection one must begin by being ignorant of a great deal. And if we understand things too quickly, perhaps we shan't understand them thoroughly.

To see a thing clearly in the mind makes it begin to take form.

A man cannot understand the art he is studying if he only looks for the end result without taking the time to delve deeply into the reasoning of the study.

Parts are not to be examined till the whole has been surveyed; there is a kind of intellectual remoteness necessary for the comprehension of any great work in its full design and its true proportions; a close approach shews the smaller niceties, but the beauty of the whole is discerned no longer.

If you get into the mental habit of relating what you’re reading to the basic structure of the underlying ideas being demonstrated, you gradually accumulate some wisdom.»
Charlie Munger11

The first was never to accept anything as true that I did not plainly know to be such; that is to say, carefully to avoid hasty judgment and prejudice; and to include nothing more in my judgments than what presented itself to my mind so clearly and so distinctly that I had no occasion to call it in doubt. The second, to divide each of the difficulties I would examine into as many parts as possible and as was required in order better to resolve them. The third, to conduct my thoughts in an orderly fashion, by commencing with those objects that are simplest and easiest to know, in order to ascend little by little, as by degrees, to the knowledge of the most composite things, and by supposing an order even among those things that do not [19] naturally precede one another. And the last, everywhere to make enumerations so complete and reviews so general that I was assured of having omitted nothing.

To understand a profound thought is to have, at the moment one understands it, a profound thought oneself; and this demands some effort, a genuine descent to the heart of oneself . . . Only desire and love give us the strength to make this effort. The only books that we truly absorb are those we read with real appetite, after having worked hard to get them, so great had been our need of them.

If you would understand anything, observe its beginning and its development

The man has to learn ‘what each specific thing means’, as Socrates often said, and stop casually applying preconceptions to individual cases.

There are indeed in some writers visible instances of deep thoughts, close and acute reasoning, and ideas well pursued. The light these would give, would be of great use, if their readers would observe and imitate them; all the rest at best are but particulars fit to be turned into knowledge, but that can be done only by our own meditation, and examining the reach, force, and coherence of what is said; and then, as far as we apprehend and see the connection of ideas, so far it is ours; without that, it is but so much loose matter floating in our brain. The memory may be stored, but the judgment is little better, and the stock of knowledge not increased, by being able to repeat what others have said or produce the arguments we have found in them. Such a knowledge as this is but knowledge by hearsay, and the ostentation of it is at best but talking by rote, and very often upon weak and wrong principles. For all that is to be found in books is not built upon true foundations, nor always rightly deduced from the principles it is pretended to be built on.

However, for the man who studies to gain <i>insight</i>, books and studies are merely rungs of the ladder on which he climbs to the summit of knowledge. As soon as a rung has raised him up one step, he leaves it behind. On the other hand, the many who study in order to fill their memory do not use the rungs of the ladder for climbing, but take them off and load themselves with them to take away, rejoicing at the increasing weight of the burden. They remain below forever, because they bear what should have bourne them.

For that school is so busied with the particles that it hardly attends to the structure, while the others are so lost in admiration of the structure that they do not penetrate to the simplicity of nature. These kinds of contemplation should therefore be alternated and taken by turns, so that the understanding may be rendered at once penetrating and comprehensive, and the inconveniences above mentioned, with the idols which proceed from them, may be avoided.

It is by tracing things to their origin, that we learn to understand them; and it is by keeping that line and that origin always in view, that we never forget them.

The man who seeks to educate himself must first read and then travel in order to correct what he has learned.
