Time-Space, Matter-Energy, Life-Evolution, Mind-Consciousness are the great
problems of science. They are always revisited to gain better understandings of their
nature, but since Plato's allegory of the cave, presented in his
Republic
, our pictures
of reality are partial, inadequate, and continuously changing. The scientist, like the
philosopher, cannot directly see the reality because he cannot stand the truth dazzle.
But the truth is under this dazzling light, everything else are only shadows, indirect
and defective realities.
