How can we integrate the scientific image of the world with our own experience of existence, without compromising either?
How can the macro-scale events of cosmology, biological evolution and cultural acquisition, which are evolving through time and have a history and a memory, be the same thing as the micro-scale events described by physics and chemistry, which remain constant, without either history or memory?
For philosophical monism to be plausible, systems at different scales must have different ordering principles. There must be asymmetries between them, so that the evolving systems at the macro-scale can co-exist with the constant systems at the micro-scale.
