theory offers a kind of response to the philosophical problem of induction. Mind Harman has also argued that perceptual experience has "intentional content" and that it is important not to confuse qualities of the intentional object of experience with qualities of the experience. Perceivers are only aware of qualities that are presented to them in experience, as opposed to properties of experience that represent what we experience as a kind of mental paint. He has also proposed that perceptual and other psychological states are self-reflective so that the content of a perceptual experience might be: this very experience is the result of perceiving a tree with such and such features (except that the experience is not in language). The content of an intention might be: this very intention will lead me to go home by six o'clock. Ethics In The Nature of Morality, Harman, relying on inference to the best explanation, argued that there are no objective moral facts because we do not need such facts to explain our moral judgments. He has argued that there is not a single true morality. In that respect, moral relativism is true. (This sort of moral relativism is not a theory about what ordinary people mean by their moral judgments.) Harman has rejected attempts to base moral theory on conceptions of human flourishing and character traits and has expressed skepticism about the need for a good person to be susceptible to moral guilt or shame.
