HEGEL said to a friend who was watching by his deathbed, "I have no one who can explain me to the world except yourself, and even you do not understand me." We are far from applying the left-handed compliment of the apostle of absolute idealism to Professor Blackie. But, touching the exposition of Platonism to this somewhat unsentimental generation, the ghost of the great Athenian idealist might appropriately address our author in the former part of the saying. Whether, in its contact with "our German brethren," it has, in its wanderings from brain to brain, caught enough of humour to fit it for the use of the latter part, it is not for us to guess. Whether the "Spirit of Plato" is worth listening to, and whether his philosophy will becomingly graft on the Scottish stock, are questions to be dealt with on the merits. Our persuasion is that we need Plato, and especially Professor Blackie's exposition of his views, both in our colleges and in our academies of art. And if Ethics and Psychology are to be only academically discussed, the one will be much the better of his genial sunny thoughts on the good; and the other would get benefit by direct, full, and warm sympathy with his views of the beautiful, the noble. We cordially thank Professor Blackie for setting our minds astir on these matters, and for his dashing and thoroughly able Discourses on Beauty. Tie brushes aside long accepted theories of the Beautiful, like so many cob-webs, and guides us straight towards those great thoughts which underlie the visible and the apparent.
