The reason is patent enough. These higher emotions to which social intercourse ministers, are of extremely complex nature; they consequently depend for their production upon very numerous conditions; the more numerous the conditions, the greater the liability that one or other of them will be disturbed, and the emotions consequently prevented. It takes a considerable misfortune to destroy appetite; but cordial sympathy with those around may be extinguished by a look or a word. Hence it follows, that the more multiplied the _unnecessary_ requirements with which social intercourse is surrounded, the less likely are its pleasures to be achieved. It is difficult enough to fulfil continuously all the _essentials_ to a pleasurable communion with others: how much more difficult, then, must it be continuously to fulfil a host of _non-essentials_ also! It is, indeed, impossible. The attempt inevitably ends in the sacrifice of the first to the last--the essentials to the non-essentials. What chance is there of getting any genuine response from the lady who is thinking of your stupidity in taking her in to dinner on the wrong arm? How are you likely to have agreeable converse with the gentleman who is fuming internally because he is not placed next to the hostess? Formalities, familiar as they may become, necessarily occupy attention--necessarily multiply the occasions for mistake, misunderstanding, and jealousy, on the part of one or other--necessarily distract all minds from the thoughts and feelings that should occupy them--necessarily, therefore, subvert those conditions under which only any sterling intercourse is to be had.
