All the things we learn, store away in our memory, and
are able to call up from our memory to examine with our
intellect are called facts. Properly speaking, they are the
elements composing the intellect of our outer, earthly
self. It is the same with memorized knowledge, which is
likewise stimulated by the beloved pleasures of our will,
though in this case the stimulus comes by way of the
intellectual side of the mind. Anything that has become
part of our will, or something we love, has been incorporated
into our life, and this is what triggers our factual
knowledge. Our inner self always has a window on
the facts we know, and delights in them, so far as they
harmonize with our passions. The facts that are fully integrated
into our passions and become spontaneous, or
natural (so to speak), disappear from our outer memory
but remain engraved on our inner memory, from which
they are never deleted. That is how facts are incorporated
into our life.
