“Dr. Watson's summary list of Sherlock Holmes's strengths and weaknesses:"1. Knowledge of Literature: Nil.2. Knowledge of Philosophy: Nil.3. Knowledge of Astronomy: Nil.4. Knowledge of Politics: Feeble.5. Knowledge of Botany: Variable. Well up in belladonna, opium, and poisons generally. Knows nothing of practical gardening.6. Knowledge of Geology: Practical but limited. Tells at a glance different soils from each other. After walks has shown me splashes upon his trousers, and told me by their colour and consistence in what part of London he had received them.7. Knowledge of Chemistry: Profound.8. Knowledge of Anatomy: Accurate but unsystematic.9. Knowledge of Sensational Literature: Immense. He appears to know every detail of every horror perpetrated in the century.10. Plays the violin well.11. Is an expert singlestick player, boxer, and swordsman.12. Has a good practical knowledge of British law.”

“If I remember rightly, you on one occasion defined my limits in a very precise fashion.""Yes," [Watson] answered, laughing. "It was a singular document. Philosophy, astronomy, and politics were marked at zero, I remember. Botany variable, geology profound as regards the mudstains from any region within fifty miles of town, chemistry eccentric, anatomy unsystematic, sensational literature and crime records unique, violin player, boxer, swordsman, lawyer, and self-poisoner by cocaine and tobacco. Those, I think, were the main points of my analysis.”

“Principles of design:1. Use both knowledge in the world and knowledge in the head.2. Simplify the structure of tasks.3. Make things visible: bridge gulfs between Execution and Evaluation.4. Get the mappings right.5. Exploit the power of constraints.6. Design for error.7. When all else fails, standardize.”

“The teaching of Colossians 2:3-8 is unambiguous. ALL knowledge (note: not simply knowledge of "religious" matters is to be found in Christ.”

“A man may possess a profound knowledge of history and mathematics; he may be an authority in psychology, biology, or astronomy; he may know all the discovered truths pertaining to geology and natural science; but if he has not with this knowledge that nobility of soul which prompts him to deal justly with his fellow men, to practice virtue and holiness in his personal life, he is not truly an educated man.Character is the aim of true education; and science, history, and literature are but means used to accomplish the desired end. Character is not the result of chance work but of continuous right thinking and right acting.”

“Knowledge was the great thing--not abstract knowledge in which Dr. Forester had been so rich, the theories which lead one enticingly on with their appearance of nobility, of transcendent virtue, but detailed, passionate, trivial human knowledge.”
