Considered as classifying ethics for Western philosophy, Aristotle proposed a system to which one could live a happy life. However, he wrote while sober. Ethics done while inebriated clouds good judgment, thus confounding the possibility for a happy life. The genesis for this typically takes place in bars late in the evening.

Nathan: I know! I can't wait to drink again so it seems OK.
