Famous quotes containing the words science and/or medicine:
“Consider the China pride and stagnant self-complacency of mankind. This generation inclines a little to congratulate itself on being the last of an illustrious line; and in Boston and London and Paris and Rome, thinking of its long descent, it speaks of its progress in art and science and literature with satisfaction.... It is the good Adam contemplating his own virtue.”
—Henry David Thoreau (18171862)
“I hold it that a little rebellion, now and then, is a good thing, and as necessary in the political world as storms in the physical.... It is a medicine necessary for the sound health of government.”
—Thomas Jefferson (17431826)
