David Deutsch Quotes

“Our best theories are not only truer than common sense, they make more sense than common sense...”

“The overwhelming majority of theories are rejected because they contain bad explanations, not because they fail experimental tests.”

“The whole scientific process resembles biological evolution. A problem is like an ecological niche, and a theory is like a gene or a species which is being tested for viability in that niche.”

“We do not experience time flowing, or passing. What we experience are differences between our present perceptions and our present memories of past perceptions. We interpret those differences, correctly, as evidence that the universe changes with time. We also interpret them, incorrectly, as evidence that our consciousness, or the present, or something, moves through time.”
