A sketch of the art of drinking might seem to announce a subject unworthy of a man whose energies have been devoted to earnest purposes and serious aims in life. But it is not my intention to make the sketch a mere treasure-box of all sorts of curiosities, nor to gratify thereby the curiosity of idle readers. When it is approached from a scientific standpoint, the dignity of science must necessarily exclude all frivolous treatment, as well as all shallow and superficial purpose. Many would be satisfied if an insignificant sketch of this kind simply bore some pathetic motto, as these words of Seneca’s: Animum aliquando debemus relaxare et quibusdam oblectamentis reficere; sed ipsa oblectamenta opera sint. I, however, would scorn a justification of this kind, for I hold that recreation ought to be recreation, and not work, and should consider it far better if our labors were pleasures, rather than our pleasures, labors.
