With M. Maeterlinck as a dramatist the world is pretty well acquainted. This little volume presents him in the new character of a philosopher and an æsthetician. And it is in some sort an 'apology' for his theatre, the one being to the other as theory to practice. Reversing the course prescribed by Mr. Squeers for his pupils, M. Maeterlinck, having cleaned w-i-n-d-e-r, winder, now goes and spells it. He began by visualising and synthetising his ideas of life; here you shall find him trying to analyse these ideas and consumed with anxiety to tell us the truth that is in him. It is not a truth for all markets; he is at no pains to conceal that. He appeals, as every mystic must, to the elect; M. Anatole France would say, to the ames bien nees. If we are not sealed of the tribe of Plotinus, he warns us to go elsewhere.
