An action that is done with knowledge of decisive reasons against it, or that derives from such a knowingly-performed prior action, constitutes or derives from genuine full-strength akrasia
akrasia(Used to motivate the pluralism debate: pluralists claim only pluralism can adequately explain this phenomenon.)
Weakness of will; the condition in which an agent knowingly chooses a less good option over a better one.
full-strength akrasia(Used as the condition required for genuine moral responsibility for bad actions)
An episode in which an agent acts against what they know to be decisive reasons, in full knowledge of every pertinent fact or norm
knowledge(Distinguished from mere true belief, which may be the product of indoctrination and need not exercise deliberative capacities.)
Justified true belief — true belief that has been arrived at through the exercise of deliberative capacities, including comparison of and deliberation among alternatives.
What must you think in order to judge that Bill, for example, is responsible for lying to his wife? You must think that at the time of action, either he knew that he had decisive reason not to lie, or if he did not know this, that his ignorance was the upshot of some prior bad action done in full knowledge of every pertinent fact or norm. You must think, in other words, that his bad action either is, or derives from, an episode of genuine, full-strength akrasia.
