Franz Boas said this quote

~ Franz Boas

Remember that in every single case in history the process of adaptation has been one of exceeding slowness. Do not look for the impossible, but do not let your path deviate from the quiet and steadfast insistence on full opportunities for your powers.

~ Franz Boas

Not so the scientist. The very essence of his life is the service of truth.
