Self-deception is so far from impossible that it is one of the most ordinary phenomena with which we are acquainted. Nothing is more usual than for a man to impute his actions to honorable motives when it is nearly demonstrable that they flowed from some corrupt and contemptible force.
By: William Godwin
The impossible often has a kind of integrity to it which the merely improbable lacks. How often have you been presented with an apparently rational explanation of something that works in all respects other than one, which is just that it is hopelessly improbable? Your instinct is to say, 'Yes, but he or she simply wouldn't do that.
By: Douglas Adams
Tis impossible to judge with much Præcision of the true Motives and Qualities of human Actions, or of the Propriety of Rules contrived to govern them, without considering with like Attention, all the Passions, Appetites, Affections in Nature from which they flow. An intimate Knowledge therefore of the intellectual and moral World is the sole foundation on which a stable structure of Knowledge can be erected.
