— Pierre Teilhard De Chardin French philosopher and Jesuit priest 1881 - 1955
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.
