  Keeping track of all of these parameters can be complicated and time consuming. Bentham does not recommend that they figure into every act of moral deliberation because of the efficiency costs which need to be considered. Experience can guide us. We know that the pleasure of kicking someone is generally outweighed by the pain inflicted on that person, so such calculations when confronted with a temptation to kick someone are unnecessary. It is reasonable to judge it wrong on the basis of past experience or consensus. One can use ‘rules of thumb’ to guide action, but these rules are overridable when abiding by them would conflict with the promotion of the good.
