The ground lost to the German school of metaphysicians was occupied during the second half of the nineteenth century by the evolutionary and positivist metaphysicians, of whom Herbert Spencer is the most notable representative. The peculiarity of this school lies in repeating at second or third hand certain idealist views, deprived of the element of pure philosophy, given to them by a Schelling or a Hegel, and in substituting a quantity of minute facts and anecdotes, with a view to providing the positivist varnish. These theories are dear to vulgar minds, because they correspond to inveterate religious beliefs, and the lustre of the varnish explains the good fortune of Spencerian positivism in our time. Another notable trait of this school is its barbaric contempt for history, especially for the history of philosophy, and its consequent lack of all link with the series composed of the secular efforts of so many thinkers. Without this link, there can be no fruitful labour and no possibility of progress. Spencer is colossal in his ignorance of all that has been written or thought on the subject of Aesthetic (to limit ourselves to this branch alone). He actually begins his work on the Philosophy of Style with these words: "No one, I believe, has ever produced a complete theory of the art of writing." This in 1852! He begins his chapter on aesthetic feelings in the _Principles of Psychology_ by admitting that he has heard of the observation made by a German author, whose name he forgets (Schiller!), on the connexion between art and play. Had Spencer's remarks on Aesthetic been written in the eighteenth century, they might have occupied a humble place among the first rude attempts at aesthetic speculation, but appearing in the nineteenth century, they are without value, as the little of value they contain had been long said by others. In his _Principles of Psychology_ Spencer looks upon aesthetic feelings as arising from the discharge of the exuberant energy of the organism. This he divides into degrees, and believes that we attain complete enjoyment when these degrees are all working satisfactorily each on its own plane, and when what is painful in excessive activity has been avoided. His degrees are sensation, sensation accompanied by representative elements, perception accompanied by more complex elements of representation, then emotion, and that state of consciousness which surpasses sensations and perceptions. But Spencer has no suspicion of what art really is. His views oscillate between sensualism and moralism, and he sees little in the whole art of antiquity, of the Middle Ages, or of modern times, which can be looked upon as otherwise than imperfect!
