„Opinion is like a pendulum and obeys the same law. If it goes past the centre of gravity on one side, it must go a like distance on the other; and it is only after a certain time that it finds the true point at which it can remain at rest.“

„In its most general form and from the point of view of physics, love is the internal, affectively apprehended, aspect of the affinity which links and draws together the elements of the world, centre to centre.“

—  Pierre Teilhard De Chardin French philosopher and Jesuit priest 1881 - 1955
Activation of Energy (1976), This is how it has been understood by the great philosophers from Plato, the poet, to Nicolas of Cusa and other representatives of frigid scholasticism. Once this definition has been accepted, it gives rise to a series of important consequences. Love is power of producing inter-centric relationship. It is present, therefore (at least in a rudimentary state), in all the natural centres, living and pre-living, which make up the world; and it represents, too, the most profound, most direct, and most creative form of inter-action that it is possible to conceive between those centres. Love, in fact, is the expression and the agent of universal synthesis. pp. 70–71 https://archive.org/stream/ActivationOfEnergy/Activation_of_Energy#page/n65/mode/2up

„The earth is not in the centre of the Sun's orbit nor at the centre of the universe, but in the centre of its companion elements, and united with them.“

—  Leonardo Da Vinci Italian Renaissance polymath 1452 - 1519
XV Astronomy, Context: The earth is not in the centre of the Sun's orbit nor at the centre of the universe, but in the centre of its companion elements, and united with them. And any one standing on the moon, when it and the sun are both beneath us, would see this our earth and the element of water upon it just as we see the moon, and the earth would light it as it lights us.

Alternating Current (1967), Context: If we are a metaphor of the universe, the human couple is the metaphor par excellence, the point of intersection of all forces and the seed of all forms.

„I am an individual … a circle touching and intersecting my neighbours at certain points, but nowhere corresponding, nowhere blending.“

—  Richard Francis Burton British explorer, geographer, translator, writer, soldier, orientalist, cartographer, ethnologist, spy, linguist, poet,… 1821 - 1890
The Kasîdah of Hâjî Abdû El-Yezdî (1870), Note I : Hâjî Abdû, The Man, Context: I am an individual … a circle touching and intersecting my neighbours at certain points, but nowhere corresponding, nowhere blending. Physically I am not identical in all points with other men. Morally I differ from them: in nothing do the approaches of knowledge, my five organs of sense (with their Shelleyan "interpenetration"), exactly resemble those of any other being. Ergo, the effect of the world, of life, of natural objects, will not in my case be the same as with the beings most resembling me. Thus I claim the right of creating or modifying for my own and private use, the system which most imports me; and if the reasonable leave be refused to me, I take it without leave. But my individuality, however all-sufficient for myself, is an infinitesimal point, an atom subject in all things to the Law of Storms called Life. I feel, I know that Fate is. But I cannot know what is or what is not fated to befall me. Therefore in the pursuit of perfection as an individual lies my highest, and indeed my only duty, the "I" being duly blended with the "We." I object to be a "self-less man," which to me denotes an inverted moral sense. I am bound to take careful thought concerning the consequences of every word and deed. When, however, the Future has become the Past, it would be the merest vanity for me to grieve or to repent over that which was decreed by universal Law.
