If the parts of the universe are subject to the law of nature, the whole universe must also be subject to it
                        Full Idea: If the parts of the universe are subject to the law of nature, then the universe itself must be subject to this law.
                        From: M. Tullius Cicero (On the Nature of the Gods ('De natura deorum') [c.44 BCE], II.86)

Why would mind mix with matter if it didn't need it?

                        A reaction: This question migrates into our puzzles about why a separate mental substance would be produced by evolution. If it is device physical systems use to promote themselves, mental substance is reduced to an inferior and dependent role.
19. Language / F. Communication / 1. Rhetoric
Eloquence educates, exhorts, comforts, distracts and unites us, and raises us from savagery
                        Full Idea: How wonderful is the power of eloquence! It enables us to learn and to teach. We use it to exhort and persuade, to comfort the unfortunate, to distract the timid and calm the passionate. It unites us in law and society, and raises us from savagery.

                        From: M. Tullius Cicero (On the Nature of the Gods ('De natura deorum') [c.44 BCE], I.44)

Chance is no more likely to create the world than spilling lots of letters is likely to create a famous poem
