…consider the phenomenon of composition and decomposition, of existence and non-existence. Every created thing in the contingent world is made up of many and varied atoms, and its existence is dependent on the composition of these. In other words, a conjunction of simple elements takes place so that from this composition a distinct organism is produced. The existence of all things is based upon this principle. But when the order is deranged, decomposition is produced and disintegration sets in, then that thing ceases to exist. That is, the annihilation of all things is caused by decomposition and disintegration. Therefore attraction and composition between the various elements is the means of life, and discord, and division produce death. Thus the cohesive and attractive forces in all things lead to the appearance of fruitful results and effects, while estrangement and alienation of things lead to disturbance and annihilation. Through affinity and attraction all living things like plants, animals and men come into existence, while division and discord bring about decomposition and destruction. 

Consequently, that which is conducive to association and attraction and unity among the sons of men is the means of the life of the world of humanity, and whatever causes division, repulsion and remoteness leads to the death of humankind.
