A great discovery does not issue from a scientist’s brain ready-made, like Minerva springing fully armed from Jupiter’s head; it is the fruit of an accumulation of preliminary work.
A fool’s brain digests philosophy into folly, science into superstition, and art into pedantry. Hence University education.
A fool with a heart and no brains is just as unhappy as a fool with brains and no heart.[Дура с сердцем и без ума такая же несчастная дура, как и дура с умом без сердца.]
