I think the problem isn't the amount of knowledge we have to assimilate in
our world, but the rate at which we can assimiliate it. Science, engineering,
and technology do not yield the 'whys' of truth; only the 'hows.' In fact,
they are not truths, but opinions from the current reigning theories of how we
think the physical world works.
