J. B. S. Haldane

Now, my own suspicion is that the universe is not only queerer than we suppose, but queerer than we can suppose.

(From his 1927 book, Possible Worlds and Other Essays.  Haldane was a British geneticist who was once asked by theologians what could be inferred from the biological world about the mind of God.  "The Creator, if he exists, has a special fondness for beetles," he famously replied, referring to the fact that there are over 400,000 species of beetles and only 8000 species of mammals.)
