In the realm of biology, the phenomenon of cell-cell recognition poses an intriguing question about the underlying nature of cellular identity. It may perhaps not come as a surprise that, when it comes to the subject of cell–cell recognition or a cell's ability to distinguish one type of neighboring cell from another, I am somewhat of a fundamentalist in that I posit that there is, in the absolute sense, only one cell which veils itself as seemingly separate cells so not to be by itself. From this holistic perspective, the notion of cell division may be seen as a misnomer. I like to think of it as cell-veiling (cell-differentiation) for the purpose of cell-companionship. While this may be construed as biological jargon, an allusion of sorts, it points to a profoundly beautiful truth that transcends all disciplinary boundaries. The simple and profound truth is that it is not good for one to be alone. The purpose of self, the meaning of life, is love. That's all there really is to it. Nothing more. Nothing less. It's fundamentally all about companionship, friendship, love.
