Several of these sins interlink, and various attempts at causal hierarchy have been made. For example, pride (love of self out of proportion) is implied in gluttony (the over-consumption or waste of food), as well as sloth, envy, and most of the others. Each sin is an attenuation of the central Christian sin of failing to love God with all resources and to love fellows as much as self. The Scholastic theologians developed schema of attribute and substance of will to explain these sins.
* Gluttony wasting of food, either through overindulgence in food, drink or intoxicants, misplaced desire for food for its sensuality, or withholding food from the needy ("excessive love of pleasure" was Dante's rendering)
