Functions are Concepts
The world of ideas is subject to the same basic outlines as the world of the physical - which in itself is largely borne of ideas that have caught on and multiplied.
Thoughts, when formed into words and communicated give us the impression of motion, movement, and work.
Ideas after utterance are functional in a mathematic sense - they add to our experience, divide us, bring us together, or remove things from a space on all levels of consciousness.
The Superconscious aspect of an idea may not always show itself upon first utterance, only to have motives revealed afterwards.
Therefore, conceive of the greatest changes. Notice where the world is unbalanced, create the functions that will reduce the remainder of the formula as you perceive it.
Ultimately - be aware of the changes you bring with you.
