of relativity. When it comes to irreducible complexity this really is in reference to biological organisms and various structures or biochemical pathways. Of course it has some relationship to causality. The cladistics or genetic maps so far indicate there is no such irreducible complexity. There really is no need for a "platonia," or a platonistic concept of structure in the universe. To be honest I tend to avoid metaphysics as much as possible. In my essay I do not address the question of whether time exists or not, but whether it plays an unexpected role as a scaling principle. I think an example of what I'm trying to say is that Barbour tries to apply the principles of focus to the universal concept of time and comes up with an ideal unit that is contradictory to his initial argument. Our ignorance may be infinite, but our stupidity is limited by the number of decisions we have to make. Not only that, but making stupid decisions tends to reduce the potential for future opportunities.
