Doubt Philosophy when superficially studied, excites doubt, when thoroughly explored, it dispels it. ~ Francis Bacon ~ There is nothing more dreadful than the habit of doubt. Doubt separates people. It is a poison that disintegrates friendships and breaks up pleasant relations. It is a thorn that irritates and hurts; it is a sword that kills. ~ Buddha ~ The fearful unbelief is unbelief in yourself. ~ Thomas Carlyle ~ Despair is the damp of hell, as joy is the serenity of heaven. ~ John Donne ~ Doubt is the father of invention. ~ Galileo Galilei ~ Doubt is a pain too lonely to know that faith is his twin brother. ~ Kahlil Gibran ~ To have doubted one's own first principles is the mark of a civilized man. ~ Oliver Wendell Holmes ~ Doubt is the beginning, not the end, of wisdom. ~ George Iles ~ Everybody in the world thought we couldn't do it. But we did, dammit. [After winning the America's Cup] ~ Bill Koch ~ An honest man can never surrender an honest doubt. ~ Walter Malone ~ The road to perseverance lies by doubt. ~ Francis Quarles ~ The whole problem with the world is that fools and fanatics are always so certain of themselves, but wiser people so full of doubts. ~ Bertrand Russell ~ Our doubts are traitors and make us lose the good we might win, by fearing to attempt.[Measure For Measure] ~ William Shakespeare ~ When in charge ponder. When in trouble delegate. When in doubt mumble. ~ Source Unknown ~ When you doubt, abstain. ~ Zoroaster ~
