If the human biological body has come to a pinnacle in its design (not incorporating genetic or molecular manipulation), then one must invariably look towards conscious development as the next realm...

individually we can see this to lie within our very own experiences:

'the purpose of human life must be to develop the entity by experience. In short, we are alive to learn...we are alive not merely to learn but also to develop our individual potential to the utmost' - Edward W. Russell - 'Design for Destiny'

And much of our experience is increasingly coming through social connectivity:

‘When we communicate and reflect among ourselves as citizens—publicly learning about and affirming our shared sentiments as an extended community—then we “know that we know.” In our dangerous and difficult time of global transition, it is not sufficient for civilizations to be wise; we must become “doubly wise” through social communication that clearly reveals our collective knowing to ourselves. Once there is a capacity for sustained and authentic social reflection, we will then have the means to achieve a shared understanding and a working consensus regarding appropriate actions for a positive future. Actions can then come quickly and voluntarily. We can mobilize ourselves purposefully, and each person can contribute his or her unique talents to building a life-affirming future. (Duane Elgin)

As our great metaphysical poet John Donne reminded us - no man is an island:

'No man is an Iland, intire of it selfe; every man is a peece of the Continent, a part of the maine; if a Clod bee washed away by the Sea, Europe is the lesse, as well as if a Promontorie were, as well as if a Mannor of thy friends or of thine owne were; any mans death diminishes me, because I am involved in Mankinde'

We are neither alone nor isolated - but must communicate, as a larger social body/organism, in order to evolve our collective consiousness. We must keep in touch.
