 The inability to imagine the separate existence of a moment is not merely a psychological limitation of the human imagination. It is instead a rational inability to separate specific logical (conceptual) contents from one another. The necessity of moments supplementing and complementing one another in the formation of a whole arises out of a necessity in the nature of the things themselves, a necessity in the sense of the moments themselves (Husserl 1900–1901 [2001: 2:11]). Consider, for example, the moral emotion of guilt: guilt involves distressing feelings about something one has done and knows or thinks to be wrong. If one tries to think away the feelings of distress, one would not recognize the emotion as guilt, and if one tries to think away the knowledge or thought that what one did was wrong, one would again not recognize the emotion as guilt. Feelings of distress and the recognition of wrongdoing are moments of—that is, essential to—guilt.
