From C. T. SENNETT
Julian Brown (Review, 8 June) thinks a Theory of Everything will make
religious explanations redundant. Hogwash yourself, Julian! A Theory of
Everything has almost negligible explanatory power. Physics does not make
chemistry redundant, nor chemistry, biology. To the engineer, Ohm’s law
rules OK, despite quantum mechanics: to the quantum chemist, quarks are
irrelevant. High-level explanations are not deduced from low-level ones
but arrived at independently. Low-level explanations occasionally interact
with the high-level ones, but the thought that a Theory of Everything will
have anything to say about right or wrong, or why we are here, is utterly
implausible.
