When two seemingly conflicting thoughts have made it to proverb or aphorism status, usually, in the ambivalence of life, both are true. – Robert Irvine Fitzhenry (1918–2008), The Harper Book of Quotations

A true quotation cannot be divorced from the character who uttered or scribbled it; it should say as much about the person quoted as about the particular subject referred to, and for this reason an anthology of quotations should be a kind of portrait gallery. – Robert Andrews, The Columbia Dictionary of Quotations, “Introduction”
