  In this essay we wish to seek a unifying thread between the basic forces. We
propose that there exists a universal force which is shared by all that
physically exists. Universality is characterized by the two properties: (i)
universal linkage and (ii) long range. They uniquely identify Einstein gravity
as the unversal force. All other forces then arise as these properties are
peeled off. For instance, relaxing (i) but retaining (ii) will lead to Maxwell
electromagnetic force. This unified outlook makes interesting suggestions and
predictions: if there exists a new force, it can only be a short range
non-abelian vector or a scalar field, and there should exist in an appropriate
space duality relations between weak and electric, and between strong and
gravity.
