“To escape from the world means that one's mind is not concerned with the opinions of the world.”

Our Christ : The Revolt of the Mystical Genius (1921)
Context: In point of fact there are two kinds sorts of mysticism, differing from one another as the ranting of drunkards from the language of illumined spirits. There is the muddled, stammering mysticism, and there is the mysticism luminous with truly ultimate ideas. On the one hand there are the empty dimness and darkness, the barren, chilling sentimentalism and mental debauchery, the foolishly grimacing but rigid phantasms of the Cabbala, of occultism, mysteriosophy and theosophy. We cannot draw too sharp a dividing line between these and the brightness, the simple sincerity, and healthy, rejuvenating strength of genuine mysticism, which takes the most precious gems from philosophy's treasure chest and displays them in the beauty of its own setting. Mysticism is in complete accord with the result, with the sum of philosophy. In fact, mysticism is precisely the sum and the soul of philosophy, in the form of that rapturous, passionate outpouring of love.... We are concerned with an understanding of this serious mysticism, and its meaning could be stated in three words... godlessness... freedom from the world... blessedness of soul.

Epistulae Morales ad Lucilium (Moral Letters to Lucilius), Letter LXXVIII: On the Healing Power of the Mind

Address to the Society of Photographic Scientists and Engineers, Los Angeles, California (5 May 1977), published Harvard Magazine (January-February 1978), pp. 23–26 <!-- , and in Zygon Vol. 16, No. 1, (1981) p. 7 - 13 -->
Context: Ordinarily when we talk about the human as the advanced product of evolution and the mind as being the most advanced product of evolution, there is an implication that we are advanced out of and away from the structure of the exterior world in which we have evolved, as if a separate product had been packaged, wrapped up, and delivered from a production line. The view I am presenting proposes a mechanism more and more interlocked with the totality of the exterior. This mechanism has no separate existence at all, being in a thousand ways united with and continuously interacting with the whole exterior domain. In fact there is no exterior red object with a tremendous mind linked to it by only a ray of light. The red object is a composite product of matter and mechanism evolved in permanent association with a most elaborate interlock. There is no tremor in what we call the "outside world" that is not locked by a thousand chains and gossamers to inner structures that vibrate and move with it and are a part of it.
The reason for the painfulness of all philosophy is that in the past, in its necessary ignorance of the unbelievable domains of partnership that have evolved in the relationship between ourselves and the world around us, it dealt with what indeed have been a tragic separation and isolation. Of what meaning is the world without mind? The question cannot exist.
