A few days back during a conversion with my friend
Qasim we started discussing Plato’s philosophy of virtue, and Qasim expressed how sometimes he felt strongly drawn by the notion that all wrongdoing springs from ignorance, and if one really
knew something was wrong, he would not do it. I must admit, the idea is not without appeal to me as well. It’s a question I’ve often asked myself as well; if I wholeheartedly believe an act to be wrong, if I know that one ought not act in such and such manner, can I then knowingly act in such and such manner?
Plato says all sin is caused by ignorance of the good. If you had known better, you would have done differently. As a immediate objection, I brought up the case of a psychopath. Apparently, I thought, a psychopath can knowingly do something wrong. Qasim was quick to point out, however, that it is only apparently so. It is not at all obvious whether a psychopath actually knows that one ought not act so and so.
Imagine a psychopath who is planning to murder his wife, because she is annoying and he’d rather get rid of her and take all her money too. The psychopath is well-aware that what he is about to do is believed by all around him to be a morally heinous act. He knows that it is believed to be an immoral act, but he feels no guilt, feels no pang of conscience, feels no inner tug of war against the temptation. Does a psychopath know that it is wrong to murder one’s wife?
There is a certain ambiguity in the word ‘know‘ here. I can separate out two usages.
A) A psychopath knows that one ought not murder one’s wife, but he lacks the internal motivation to avoid doing so.
B) A psychopath does not know that one ought not murder one’s wife.
There is a subtle difference in the knowing in A and B. The knowing in A is the ordinary and common sense use of the word. A psychopath knows (A) that one ought not murder one’s wife because he understands the imperative. The knowing in B is in the Platonic sense.
If we consider sentence A to be equivalent to sentence B, then it means that
knowing (B) = knowing (A) + internal motivation
Let us see if the case of the psychopath (P) is different from that of a “normal” individual (N) when it comes to Platonic moral knowledge.
A psychopath is consciously planning to murder his wife. He does not know that what he is doing is morally wrong.
A normal individual is consciously planning to murder his wife. He does not know that what he is doing is morally wrong.
What then is the difference between the two? Is there no difference at all between the murder committed by a psychopath and murder committed by a normal person? If there is, where does it lie?
It needs to qualified, I’d say. Perhaps the difference is that a normal person actually
does believe that what he is doing is morally wrong, but he is able to suppress and ignore it long enough to commit the act. The not-knowing of N resides in a suppression of his internal imperative to do good and avoid evil. This is supported by the fact that a normal person is capable of guilt and regret over his crime. If a normal person did know better, he would not have committed the act. A psychopath, on the other hand, has no such belief; he is not suppressing or ignoring anything. He is not capable of guilt and regret over what he did. The not-knowing of P is in the absence of an internal imperative. For the psychopath, there is nothing to know better.
