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?
