The essence of being human is that one does not seek perfection, that one is sometimes willing to commit sins for the sake of loyalty, that one does not push asceticism to the point where it makes friendly intercourse impossible, and that one is prepared in the end to be defeated and broken up by life, which is the inevitable price of fastening one's love upon other human individuals...It is too readily assumed...that the ordinary man only rejects [saintliness] because it is too difficult: in other words, that the average human being is a failed saint. It is doubtful whether this is true. Many people genuinely do not wish to be saints, and it is probable that some who achieve or aspire to sainthood have never felt much temptation to be human beings.
Giving up alcohol is an asceticism for the modern do-gooder, drinking being, like sex, a pleasure that humans have always indulged in, involving a loss of self-control, the renunciation of which marks the renouncer as different and separate from other people. To drink, to get drunk, is to lower yourself on purpose for the sake of good fellowship. You abandon yourself, for a time, to life and fate. You allow yourself to become stupider and less distinct. Your boundaries become blurry: you open your self and feel connected to people around you. You throw off your moral scruples, and suspect it was only those scruples that prevented the feeling of connection before. You feel more empathy for your fellow, but at the same time, because you are drunk, you render yourself unable to help him; so, to drink is to say, I am a sinner, I have chosen not to help.
