Abstract
In this paper I will first bring out some linguistic difficulties which suggest that the notions of benefit and harm are not as straightforwardly univocal as one might have thought, and then go on to make some distinctions within these notions which will bring to light their complexities, and help to clarify the relation between the good and the beneficial. The notion of the good and of the bene- ficial that are being used here are tied to human happiness. There are other conceptions of the good of man, and I may be mistaken in connecting it exclusively with human happiness, but the logical points concerning the concepts of benefit and harm will not be directly affected by this.
