"The production of all works in art or poetry requires, in their conception and execution, not only an exercise of the intellect, skill, and patience, but particularly a concurrent warmth of feeling and a free flow of imagination. This renders them most tender plants, which will thrive only in an atmosphere calculated to maintain that warmth, and that atmosphere is one of kindness—kindness towards the artist personally as well as towards his production. An unkind word of criticism passes like a cold blast over their tender shoots, and shrivels them up, checking the flow of the sap, which was rising to produce, perhaps, multitudes of flowers and fruit."
