Syntropy

A Greek derived word meaning ‘growth of convergence’ or ‘tendency to grow together’.
From Greek ‘syn’ together, ‘tropos’ tendency. It was first coined by the mathematician Luigi Fantappiè, in 1941, in order to describe the mathematical properties of the advanced waves solution of the Klein-Gordon equation which unites Quantum Mechanics with Special Relativity. As noted by Viterbo, syntropy is "the tendency towards energy concentration, order, organization and life". In contradistinction to "entropy," syntropy is a result of retrocausality leading to persistent and more complex organization.
In Biology syntropy  is the occasional tendency of two diseases to coalesce into one. The psychological state of wholesome association with others. A number of similar structures inclined in one general direction, such as the ribs.
