“Look out, Loretta.”

Variants of "the Four Mottos":
Look up and not down;
Look out and not in.
Look forward and not back;
Lend a hand!
As used in Our New Crusade (1884)
Look up and not down;
Look forward and not back;
Look out and not in; —
Lend a hand!

Variant translations of first portion: A book is a mirror: If an ape peers into it, you can't expect an apostle to look out.
A book is a mirror: If an ass peers into it, you can't expect an apostle to look out. — this has actually been the most commonly cited form, but it is based on either a loose non-literal translation or a mistranslation of the German original: Ein Buch ist Spiegel, aus dem kein Apostel herausgucken kann, wenn ein Affe hineinguckt.
Aphorisms (1765-1799), Notebook E (1775 - 1776)
Context: A book is a mirror: if an ape looks into it an apostle is hardly likely to look out. We have no words for speaking of wisdom to the stupid. He who understands the wise is wise already.

Iraq? They just need to think it through (2007)
Context: What happened was, 2,400 years ago, the Greek Gang of Three, by whom I mean Aristotle, Plato and Socrates, started to think based on analysis, judgment and knowledge. At the same time, church people, who ran the schools and universities, wanted logic to prove the heretics wrong. As a result, design and perceptual thinking was never developed. People assumed philosophers were doing it and so they blocked anyone else from doing it. But philosophers were not. Philosophers may look out at the world from a stained-glass window, but after a while they stop looking at the world and start looking at the stained glass.
