Robinson Jeffers quote: “Here is a symbol in which Many high tragic thoughts Watch their own eyes.”

“Many but not all my cannabis trips have somewhere in them a symbolism significant to me which I won't attempt to describe here, a kind of mandala embossed on the high.”

Carl Sagan (1934–1996) American astrophysicist, cosmologist, author and science educator

Essay as "Mr. X" (1969)
Context: When I'm high I can penetrate into the past, recall childhood memories, friends, relatives, playthings, streets, smells, sounds, and tastes from a vanished era. I can reconstruct the actual occurrences in childhood events only half understood at the time. Many but not all my cannabis trips have somewhere in them a symbolism significant to me which I won't attempt to describe here, a kind of mandala embossed on the high. Free-associating to this mandala, both visually and as plays on words, has produced a very rich array of insights.
There is a myth about such highs: the user has an illusion of great insight, but it does not survive scrutiny in the morning. I am convinced that this is an error, and that the devastating insights achieved when high are real insights; the main problem is putting these insights in a form acceptable to the quite different self that we are when we're down the next day.

“To present a visible symbol to the eye of another, is not necessarily to inform him of the meaning which that symbol has to you.”

Albert Pike book Morals and Dogma of the Ancient and Accepted Scottish Rite of Freemasonry

Source: Morals and Dogma of the Ancient and Accepted Scottish Rite of Freemasonry (1871), Ch. III : The Master, p. 63
Context: To present a visible symbol to the eye of another, is not necessarily to inform him of the meaning which that symbol has to you. Hence the philosopher soon superadded to the symbols explanations addressed to the ear, susceptible of more precision, but less effective and impressive than the painted or sculptured forms which he endeavored to explain. Out of these explanations grew by degrees a variety of narrations, whose true object and meaning were gradually forgotten, or lost in contradictions and incongruities. And when these were abandoned, and Philosophy resorted to definitions and formulas, its language was but a more complicated symbolism, attempting in the dark to grapple with and picture ideas impossible to be expressed. For as with the visible symbol, so with the word: to utter it to you does not inform you of the exact meaning which it has to me; and thus religion and philosophy became to a great extent disputes as to the meaning of words. The most abstract expression for Deity, which language can supply, is but a sign or symbol for an object beyond our comprehension, and not more truthful and adequate than the images of Osiris and Vishnu, or their names, except as being less sensuous and explicit We avoid sensuousness, only by resorting to simple negation. We come at last to define spirit by saying that it is not matter. Spirit is — spirit.

“Take the birds which you'll have noticed in so many of my recent paintings. I never thought them up, they just materialized of their own accord, they were born on the canvas; that is why it is absurd to read any sort of symbolic significance into them.”

Georges Braque (1882–1963) French painter and sculptor

1946 - 1963, interview with John Richardson' (1957)

“When the Artist rises high enough to achieve the Beautiful, the symbol by which he makes it perceptible to mortal senses becomes of little value in his eyes, while his spirit possesses itself in the enjoyment of the reality.”

Nathaniel Hawthorne (1804–1864) American novelist and short story writer (1804 – 1879)

As quoted in "Hawthorne and His Mosses" (1851) http://www.eldritchpress.org/nh/hahm.html by Herman Melville

“That tragic and intractable phenomenon which we watch with horror on the other side of the Atlantic but which there is interwoven with the history and existence of the States itself, is coming upon us here by our own volition and our own neglect. Indeed, it has all but come. In numerical terms, it will be of American proportions long before the end of the century. Only resolute and urgent action will avert it even now. Whether there will be the public will to demand and obtain that action, I do not know. All I know is that to see, and not to speak, would be the great betrayal.”

Enoch Powell (1912–1998) British politician

The 'Rivers of Blood' speech

“Don Quixote made himself ridiculous; but did he know the most tragic ridicule of all, the inward ridicule, the ridiculousness of a man's self to himself, in the eyes of his own soul?”

Miguel de Unamuno (1864–1936) 19th-20th century Spanish writer and philosopher

The Tragic Sense of Life (1913), Conclusion : Don Quixote in the Contemporary European Tragi-Comedy
Context: Don Quixote made himself ridiculous; but did he know the most tragic ridicule of all, the inward ridicule, the ridiculousness of a man's self to himself, in the eyes of his own soul? Imagine Don Quixote's battlefield to be his own soul; imagine him to be fighting in his soul to save the Middle Ages from the Renaissance, to preserve the treasure of his infancy; imagine him an inward Don Quixote, with a Sancho at his side, inward and heroic too — and tell me if you find anything comic in the tragedy.

“Over his own heart and his own thoughts he watched attentively. He knew not whither his longing was carrying him.”

Novalis (1772–1801) German poet and writer

Pupils at Sais (1799)
Context: Over his own heart and his own thoughts he watched attentively. He knew not whither his longing was carrying him. As he grew up, he wandered far and wide; viewed other lands, other seas, new atmospheres, new rocks, unknown plants, animals, men; descended into caverns, saw how in courses and varying strata the edifice of the Earth was completed, and fashioned clay into strange figures of rocks. By and by, he came to find everywhere objects already known, but wonderfully mingled, united; and thus often extraordinary things came to shape in him. He soon became aware of combinations in all, of conjunctures, concurrences. Erelong, he no more saw anything alone. — In great variegated images, the perceptions of his senses crowded round him; he heard, saw, touched and thought at once. He rejoiced to bring strangers together. Now the stars were men, now men were stars, the stones animals, the clouds plants; he sported with powers and appearances; he knew where and how this and that was to be found, to be brought into action; and so himself struck over the strings, for tones and touches of his own.
