„Don't just read it; fight it! Ask your own question, look for your own examples, discover your own proofs. Is the hypothesis necessary? Is the converse true? What happens in the classical special case? What about the degenerate cases? Where does the proof use the hypothesis?“

„By and large, by asking the question "what use is it?" you are asking the animal to justify its existence without having justified your own.“

—  Gerald Durrell naturalist, zookeeper, conservationist, author and television presenter 1925 - 1995

Two in the Bush (1966)
Contexto: The attitude of the average person to the world they live in is completely selfish. When I take people round to see my animals, one of the first questions they ask (unless the animal is cute and appealing) is, "what use is it?" by which they mean, "what use is it to them?" To this one can reply "What use is the Acropolis?" Does a creature have to be of direct material use to mankind in order to exist? By and large, by asking the question "what use is it?" you are asking the animal to justify its existence without having justified your own.

„Those who raise questions about the God hypothesis and the soul hypothesis are by no means all atheists.“

—  Carl Sagan American astrophysicist, cosmologist, author and science educator 1934 - 1996

Conversations with Carl Sagan (2006) http://books.google.ca/books?id=gJ1rDj2nR3EC&pg=PA70&redir_esc=y#v=onepage&q&f=false, edited by Tom Head, p. 70
Contexto: Those who raise questions about the God hypothesis and the soul hypothesis are by no means all atheists. An atheist is someone who is certain that God does not exist, someone who has compelling evidence against the existence of God. I know of no such compelling evidence. Because God can be relegated to remote times and places and to ultimate causes, we would have to know a great deal more about the universe than we do to be sure that no such God exists. To be certain of the existence of God and to be certain of the nonexistence of God seem to me to be the confident extremes in a subject so riddled with doubt and uncertainty as to inspire very little confidence indeed.

„Look in; and learn the wrong, and right,
From your own soul's unwritten laws.
And when you question, or demur,
Let Love be your Interpreter.“

Contexto: Look to the Great Eternal Cause
And not to any man, for light.
Look in; and learn the wrong, and right,
From your own soul's unwritten laws.
And when you question, or demur,
Let Love be your Interpreter.

„HOW TO LEARN ANYTHINGAs far as I can tell these are the techniques used by bright people who want to learn something other than by taking courses in it. […]1. DECIDE WHAT YOU WANT TO LEARN. But you can't know this exactly, because you don't know exactly how any field is structured until you know all about it.2. READ EVERYTHING YOU CAN ON IT, especially what you enjoy, since that way you can read more of it and faster.3. GRAB FOR INSIGHTS. Regardless of points others are trying to make, when you recognize an insight that has meaning for you, make it your own […] Its importance is not how central it is, but how clear and interesting and memorable to you. REMEMBER IT. Then go for another.4. TIE INSIGHTS TOGETHER. Soon you will have your own string of insights in a field. […]5. CONCENTRATE ON MAGAZINES, NOT BOOKS. Magazines have far more insights per inch of text, and can be read much faster. But when a book really speaks to you, lavish attention on it.6. FIND YOUR OWN SPECIAL TOPICS, AND PURSUE THEM.7. GO TO CONVENTIONS. For some reason, conventions are a splendid concentrated way to learn things; talking to people helps. […]8. "FIND YOUR MAN." Somewhere in the world is someone who will answer your questions extraordinarily well. If you find him, dog him. […]9. KEEP IMPROVING YOUR QUESTIONS. Probably in your head there are questions that don't seem to line up with what your hearing. Don't assume that you don't understand; keep adjusting the questions till you get an answer that relates to what you wanted.10. YOUR FIELD IS BOUNDED WHERE YOU WANT IT TO BE. Just because others group and stereotype things in conventional ways does not mean they are necessarily right. Intellectual subjects are connected every which way; your field is what you think it is. […]“
