The causalism that underlies our scientific picture of the world breaks everything down into individual processes which it punctiliously tries to isolate from all other parallel processes.

This tendency is absolutely necessary if we are to gain a reliable knowledge of the world; but philosophically it has the disadvantage of breaking up, or obscuring, the universal interrelationship of events so that a recognition of the greater relationship, i.e., the unity of the world, becomes more and more difficult.

Everything that happens, however, happens in the same “one world” and is part of it.

For this reason events must have an a priori aspect of unity. ~Carl Jung, Mysterium Coniunctionis, Para 663
