People's conceptions about themselves and the nature of things are developed and verified through four different processes: direct experience of the effects produced by their actions, vicarious experience of the effects produced by somebody else's actions, judgments voiced by others, and derivation of further knowledge from what they already know by using rules of inference
Albert BanduraWhen people are not aiming for anything in particular or when they cannot monitor their performance, there is little basis for translating perceived efficacy into appropriate magnitudes of effort
Albert BanduraMost of the images of reality on which we base our actions are really based on vicarious experience.
Albert BanduraMoral justification is a powerful disengagement mechanism. Destructive conduct is made personally and socially acceptable by portraying it in the service of moral ends. This is why most appeals against violent means usually fall on deaf ears.
