Mark Twain quote - ring any bells?

When the doctrine of allegiance to party can utterly up-end a man's moral constitution and make a temporary fool of him besides, what excuse are you going to offer for preaching it, teaching it, extending it, perpetuating it? Shall you say, the best good of the country demands allegiance to party? Shall you also say it demands that a man kick his truth and his conscience into the gutter, and become a mouthing lunatic, besides?

[from: "Consistency", paper read at the Hartford Monday Evening Club on 5 December 1887. See WikiQuote]
