„Perhaps the topic [of this book] will appear fairly difficult to you because it is not yet familiar knowledge and the understanding of beginners is easily confused by mistakes; but with your inspiration and my teaching it will be easy for you to master, because clear intelligence supported by good lessons is a fast route to knowledge.“

Following the dedication to Dionysus as quoted by Paul Drijvers, Secondary Algebra Education (2011)

„Do not be arrogant because of your knowledge, but confer with the ignorant man as with the learned. For knowledge has no limits, and none has yet achieved perfection in it.“

—  Ptahhotep Ancient Egyptian vizier

Maxim no .1.
Context: Do not be arrogant because of your knowledge, but confer with the ignorant man as with the learned. For knowledge has no limits, and none has yet achieved perfection in it. Good speech is more hidden than malachite, yet it is found in the possession of women slaves at the millstones.

„All “inspired books,” teaching that what the supernatural commands is right, and right because commanded, and that what the supernatural prohibits is wrong, and wrong because prohibited, are absurdly unphilosophic.“

—  Robert G. Ingersoll Union United States Army officer 1833 - 1899

What Would You Substitute for the Bible as a Moral Guide? (1900)
Context: All “inspired books,” teaching that what the supernatural commands is right, and right because commanded, and that what the supernatural prohibits is wrong, and wrong because prohibited, are absurdly unphilosophic. And all “inspired books,” teaching that only those who obey the commands of the supernatural are, or can be, truly virtuous, and that unquestioning faith will be rewarded with eternal joy, are grossly immoral. Again I say: Intelligence is the only moral guide.
