Ebook Marks of a Clear Mind

As I urge again and again throughout this book and throughout all my 'books, science is only a small part of life; it is only one approach to truth; but in its own domain it is supreme. It can brook no rival. It knows no mercy; it is utterly inhuman. It knows no friends, no enemies; it has no heart, no emotion, no passion, except one, the passion to think straight, the passion not to be fooled, and not to fool any one else. There is nothing mysterious about it at all. Indeed its whole passion is to remove mystery, to replace mystery with knowledge.
