The author presents and defends three theses: (1) "the first is that it is not profitable for us at present to do moral philosophy; that should be laid aside at any rate until we have an adequate philosophy of psychology." (2) "the second is that the concepts of obligation, And duty... And of what is morally right and wrong, And of the moral sense of 'ought', Ought to be jettisoned if this is psychologically possible...." (3) "the third thesis is that (...) the differences between the well-Known english writers on moral philosophy from sidgwick to the present day are of little importance." (staff). (shrink)

A central problem in moral theory is how it is to be defended against those who think that there is no harm in being immoral, and that immorality can be in one's self-interest, assuming the perpetrator is not caught and punished. The argument presented here defends the idea that being immoral prevents one from having self-respect. If it makes sense to think that one cannot be happy without self-respect, then the conclusion follows that one cannot be both immoral and happy. (...) Immorality is harmful because its self-disrespecting nature keeps immoralists from being happy. This is the harm of immorality. (shrink)
