“Connection can be thought of as a link formed with something or someone else. If you are linked to something, you cannot affect it without affecting yourself. And this is really the greatest form of safety available on the planet or any living being.”

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.

Language Education in a Knowledge Context (1980)
Context: It is precisely through one's learning about the total context in which the language of a subject is expressed that personality may be altered. If one learns how to speak history or mathematics or literary criticism, one becomes, by definition, a different person. The point to be stressed is that a subject is a situation in which and through which people conduct themselves, largely in language. You cannot learn a new form of conduct without changing yourself.

Draft for a Statement of Human Obligation (1943)
Context: The combination of these two facts — the longing in the depth of the heart for absolute good, and the power, though only latent, of directing attention and love to a reality beyond the world and of receiving good from it — constitutes a link which attaches every man without exception to that other reality.
Whoever recognizes that reality recognizes also that link. Because of it, he holds every human being without any exception as something sacred to which he is bound to show respect.
This is the only possible motive for universal respect towards all human beings. Whatever formulation of belief or disbelief a man may choose to make, if his heart inclines him to feel this respect, then he in fact also recognizes a reality other than this world's reality. Whoever in fact does not feel this respect is alien to that other reality also.
