Harry Frankfurt – On Bullshit (1986)

Bullshit is unavoidable whenever circumstances require someone to talk without knowing what he is talking about.

John Milton – Paradise Lost (1674)

…Knowledge forbidd’n?
Suspicious, reasonless. Why should thir Lord
Envie them that? can it be sin to know,
Can it be death? and do they onely stand
By Ignorance, is that thir happie state,
The proof of thir obedience and thir faith?

Hence will I excite thir minds
With more desire to know, and to reject
Envious commands, invented with designe
To keep them low whom knowledge might exalt
Equal with Gods;…

(wherein Milton tries to make curiosity the bogeyman by giving one of the most thoughtful passages to Satan)

Christopher Hitchens – Hitch-22 (2010)

It is not only true that the test of knowledge is an acute and cultivated awareness of how little one knows (as Socrates knew so well), it is true that the unbounded areas and fields of one’s ignorance are now expanding in such a way, and at such a velocity, as to make the contemplation of them almost fantastically beautiful.

Leslie Stephen – An Agnostic’s Apology (1893)

We are a company of ignorant beings, feeling our way through mists and darkness, learning only by incessantly repeated blunders, obtaining a glimmering of truth by falling into every conceivable error, dimly discerning light enough for our daily needs, but hopelessly differing whenever we attempt to describe the ultimate origin or end of our paths; and yet when one of us ventures to declare that we don’t know the map of the universe as well as the map of our infinitesimal parish, he is hooted, reviled, and perhaps told that he will be damned to all eternity for his faithlessness.

(quoted in The Portable Atheist)

Charles Darwin – The Descent of Man (1871)

The judgment of the community will generally be guided by some rude experience of what is best in the long run for all the members; but this judgment will not rarely err from ignorance and weak powers of reasoning. Hence the strangest customs and superstitions, in complete opposition to the true welfare and happiness of mankind, have become all-powerful throughout the world….

How so many absurd rules of conduct, as well as so many absurd religious beliefs, have originated, we do not know; nor how it is that they have become, in all quarters of the world, so deeply impressed on the mind of men; but it is worthy of remark that a belief constantly inculcated during the early years of life, while the brain is impressible, appears to acquire almost the nature of an instinct; and the very essence of an instinct is that it is followed independently of reason.

Alan Lightman – Dance for Two (1996)

…Eventually, a large fraction of the trillion neurons in the man’s brain become involved with computing the visual and auditory data just acquired. Sodium and potassium gates open and close. Electrical currents speed along neuron fibers. Molecules flow from one nerve ending to the next.

All of this is known. What is not known is why, after about a minute, the man walks over to the woman and smiles.

Carl Sagan – The Demon-Haunted World (1995)

We’ve arranged a global civilization in which most crucial elements – transportation, communications, and all other industries; agriculture, medicine, education, entertaining, protecting the environment; and even the key democratic institution of voting – profoundly depend on science and technology. We have also arranged things so that almost no one understands science and technology. This is a prescription for disaster. We might get away with it for a while, but sooner or later this combustible mixture of ignorance and power is going to blow up in our faces.

Carl Sagan – The Demon-Haunted World (1995)

Science is more than a body of knowledge; it is a way of thinking. I have a foreboding of an America in my children’s or grandchildren’s time – when the United States is a service and information economy; when nearly all the key manufacturing industries have slipped away to other countries; when awesome technological powers are in the hands of a very few, and no one representing the public interest can even grasp the issues; when the people have lost the ability to set their own agendas or knowledgeably question those in authority; when, clutching our crystals and nervously consulting our horoscopes, our critical faculties in decline, unable to distinguish between what feels good and what’s true, we slide, almost without noticing, back into superstition and darkness.

Carl Sagan – The Demon-Haunted World (1995)

Emerging from a particularly credulous Southern California culture, Nancy and Ronald Reagan relied on an astrologer in private and public matters – unknown to the voting public. Some portion of the decision-making that influences the future of our civilization is plainly in the hands of charlatans.

Charles Darwin – Descent of Man (1871)

It has often and confidently been asserted that man’s origin can never be known; but ignorance more frequently begets confidence than does knowledge; it is those who know little, and not those who know much, who so positively assert that this or that problem will never be solved by science.
