If evil Men speak good, or good Men evil of thee; examine thy Actions, and suspect thy self: But if evil Men speak evil of thee; hold it as an Honor, and by way of Thankfulness love them; but upon condition, that they continue to hate thee.

Thomas Fuller (1654-1734) English physician, preacher, aphorist, writer

Introductio ad Prudentiam, Vol. 1, # 1252 (1725)
