This is an age of intellectual sauces, of essence, of distillation. We have conclusions without deductions, abridgments of history and abridgments of science without leading facts. We have animals for literature, Cabinet Encyclopaedias, Family Libraries, Diffusion Societies, and heaven knows what else! What is all this for? Not to add knowledge to the learned, but to tell points to the ignorant, without giving them the trouble to acquire the links. Oh! it is sad work. And the result will be injurious to all classes.
