It's a vice to trust all, and equally a vice to trust none

Vice may be learnt, even without a teacher.

Those vices [luxury and neglect of decent manners] are vices of men, not of the times. [Lat., Hominum sunt ista [vitia], non temporum.

Never trust a man without vices...

I don't trust liberals, I trust conservatives.

I am a Ford, not a Lincoln." (On becoming vice president, December 1973)
