This article considers the relation hating to loving. After distinguishing feelings (i.e., loving, hating, etc.) and feeling-states (hatred, joy, anger, rage, sadness, etc.), I describe how hating and loving as acts are related to one another. Following upon a phenomenological distinction between grounding and founding relations, I consider various relations of foundation. I suggest in the final analysis that loving and hating are not coeval or parallel acts. Rather, hating is founded in loving. More precisely still, hating is founded in loving as moving contrary to loving.
