These are primitive beginnings in art, such as one usually finds in ethnographic collections or at home in one's nursery. Do not laugh, reader! Children also have artistic ability, and there is wisdom in their having it! The more helpless they are, the more instructive are the examples they furnish us; and they must be preserved from corruption at an early age. Parallel phenomena are provided by the works of the mentally diseased; neither childish behaviour nor madness are insulting words here, as they commonly are. All this is to be taken very seriously, more seriously than all the public galleries, when it comes to reforming today's art.
