There is an inconvenience which attends all abstruse reasoning. that it may silence, without convincing an antagonist, and requires the same intense study to make us sensible of its force, that was at first requisite for its invention. When we leave our closet, and engage in the common affairs of life, its conclusions seem to vanish, like the phantoms of the night on the appearance of the morning; and 'tis difficult for us to retain even that conviction, which we had attain'd with difficulty.

Part 1 Of virtue and vice in general, Sect. 1 Moral distinctions not deriv'd from reasonDavid Hume
Silence is difficult and arduous, it is not to be played with. It isn't something that you can experience by reading a book, or by listening to a talk, or by sitting together, or by retiring into a wood or a monastery. I am afraid none of these things will bring about this silence. This silence demands intense psychological work. You have to be burningly aware of your snobbishness, aware of your fears, your anxieties, your sense of guilt. And when you die to all that, then out of that dying comes the beauty of silence.
Jiddu Krishnamurti
It is a common experience that a problem difficult at night is resolved in the morning after the committee of sleep has worked on it.
John Steinbeck
I know that most men — not only those considered clever, but even those who are very clever and capable of understanding most difficult scientific, mathematical, or philosophic, problems — can seldom discern even the simplest and most obvious truth if it be such as obliges them to admit the falsity of conclusions they have formed, perhaps with much difficulty — conclusions of which they are proud, which they have taught to others, and on which they have built their lives.
Leo Tolstoy
If reason (I mean abstract reason, derived from inquiries a priori) be not alike mute with regard to all questions concerning cause and effect, this sentence at least it will venture to pronounce, That a mental world, or universe of ideas, requires a cause as much, as does a material world, or universe of objects; and, if similar in its arrangement, must require a similar cause. For what is there in this subject, which should occasion a different conclusion or inference? In an abstract view, they are entirely alike; and no difficulty attends the one supposition, which is not common to both of them.
David Hume
What makes a subject difficult to understand — if it is significant, important — is not that some special instruction about abstruse things is necessary to understand it. Rather it is the contrast between the understanding of the subject and what most people want to see. Because of this the very things that are most obvious can become the most difficult to understand. What has to be overcome is not difficulty of the intellect but of the will.
