from a great class of concrete objects its uniting quality, its common characteristic, and formulate this apart from the objects themselves. I have sometimes taken the triangle as the very simplest image which thought can form. You may have triangles of any size, you may have triangles of almost any shape, provided only three lines are used, and those lines are right lines, or unbent. What is the governing characteristic of the triangle? That its three angles, formed by the meeting of enclosing sides, must be equal to two right angles. Now supposing that you have the power of brain, the power of abstraction, to take ten, twenty or thirty concrete triangles and hold them in the mind as though you were looking at them in outer form, to create their mental images so that every form is present in your mind, you directing your attention to them all at the same time, then--if out of these many concrete objects that have the particular properties in common of the three right lines that enclose and the sum of the three angles equalling two right angles--if you can draw out the idea of that common property, separated from every concrete triangle, and make it an object in consciousness, then you will have risen from the concrete to the abstract, and will have some idea of what is meant by an archetype in the higher world. The earliest actions of the Deity in evolving a system are of this nature; He generates certain types or archetypes, and by the sub-division and multiplication of these the whole universe of concrete objects is formed; each one of them is capable of generating innumerable forms that reproduce its own characteristic amid endless diversities of subsidiary properties.
