Quote from Lee Smolin in Scientific American:
There are some lazy ideas about unification that reflect uncritical thinking, such as the idea that the more fundamental a phenomena [sic] is the more symmetry it must have. When you think seriously about the problem you realize it must be exactly the opposite. Roger Penrose use to say this, and indeed the insight that the most fundamental theory can have no symmetries goes back to Leibniz.
Also does anyone know what exactly Leibniz had to say on the matter?
