Who bites against the new bit in his teeth,
And tugs and struggles against the new-tried rein.”

“Trying to define yourself is like trying to bite your own teeth.”
As quoted in Life magazine (21 April 1961)

1860s, Cooper Union speech (1860)
Context: You say you are conservative — eminently conservative — while we are revolutionary, destructive, or something of the sort. What is conservatism? Is it not adherence to the old and tried, against the new and untried? We stick to, contend for, the identical old policy on the point in controversy which was adopted by "our fathers who framed the Government under which we live;" while you with one accord reject, and scout, and spit upon that old policy, and insist upon substituting something new. True, you disagree among yourselves as to what that substitute shall be. You are divided on new propositions and plans, but you are unanimous in rejecting and denouncing the old policy of the fathers.
