 * Ignorance never settles a question.
 * Benjamin Disraeli, speech, House of Commons (May 14, 1866).


 * In Western society... [t]here are no more continents... little left to discover. I am, in part, an ant biologist... and I knew that much of the world of insects remains unknown. ...How ignorant are we? The question of what we know and do not know clung to me. ...In looking into the stories of biological discovery, I... began to find... a collection of scientists, often obsessive, usually brilliant, occasionally half-mad... Those individuals very often see the same things that other scientists see, but they pay more attention... and they focus on them to the point of exhaustion, and at the risk of the ridicule of their peers. ...[W]e are, before these discoveries, always more ignorant than we imagine ourselves to be. ...[W]e are repeatedly willing to imagine we have found most of what is left to discover. Before microbes were discovered, scientists were confident that insects were the smallest organisms. Before life was discovered at the bottom of the ocean, many scientists were confident that nothing lived deeper than three hundred fathoms. Once we made a tree of life that included four kingdoms (animals, plants, fungi, and s), we were confident that there would be no more major branches to reveal. ...We are again at a stage when we believe we have found most of what might be found, but we are wrong. ...[W]hole realms of life remain to be found. ...And even before a new realm or kind of life is found, we still have to explore the realms we have already discovered. Most species on Earth are not yet named. Most named species have not yet been studied. When we lived in small communities, hunting and gathering, we knew only the animals and plants around us, particularly those... useful or dangerous. Living on the thin green surface of our small planet in a universe full of stars, we are not so different today. The wild leaps up and more often than not we do not event know its name.

 * If I had to name the single most frightening and dangerous threat to the health of the oceans, the one that stands alone yet is at the base of all the others is ignorance: lack of understanding, a failure to relate our destiny to that of the sea, or to make the connection between the health of coral reefs and our own health, between the fate of the great whales and the future of humankind. There is much to learn before it is possible to intelligently create a harmonious, viable place for ourselves on the planet. The best place to begin is by recognizing the magnitude of our ignorance, and not destroy species and natural systems that we cannot re-create nor effectively restore once they are gone.
 * Sylvia Earle Sea Change: A Message of the Oceans (1995)


 * Ignorance gives one a large range of probabilities.

 * Oliver Goldsmith, The Deserted Village (1770), line 61.


 * To each his suff’rings; all are men, Condemn’d alike to groan,— The tender for another’s pain, Th’ unfeeling for his own. Yet ah! why should they know their fate, Since sorrow never comes too late, And happiness too swiftly flies? Thought would destroy their paradise. No more; where ignorance is bliss, ’T is folly to be wise.

 * There appears to be a discrepancy between the importance/self-relevance of social issues and people’s willingness to engage with and learn about them... Ignorance — as a function of the system justifying tendencies it may activate—may, ironically, breed more ignorance.

 * It has become clear that people turn to their external systems to regulate a number of relational, existential, and epistemic threats... We leveraged this past research to develop a novel explanation for how people’s tendency to trust in their social systems, and outsource their worries and fears to these systems, can lead to the propagation of ignorance in the context of important social issues.

 * Softmindedness often invades religion. … Softminded persons have revised the Beautitudes to read "Blessed are the pure in ignorance: for they shall see God." This has led to a widespread belief that there is a conflict between science and religion. But this is not true. There may be a conflict between softminded religionists and toughminded scientists, but not between science and religion. … Science investigates; religion interprets. Science gives man knowledge which is power; religion gives man wisdom which is control. Science deals mainly with facts; religion deals mainly with values. The two are not rivals. They are complementary.
 * Martin Luther King, Jr., in Strength to Love (1963), Ch. 1 : A tough mind and a tender heart


 * There is little hope for us until we become toughminded enough to break loose from the shackles of prejudice, half-truths, and downright ignorance. The shape of the world today does not permit us the luxury of softmindedness.
 * Martin Luther King, Jr., in Strength to Love (1963), Ch. 1 : A tough mind and a tender heart


 * Ignorance is a kind of insanity in the human animal. People who delight in torturing defenseless children or tiny creatures are in reality insane. The terrible thing is that people who are madmen in private may wear a totally bland and innocent expression in public.
 * Akira Kurosawa 'Something Like an Autobiography'' (1981)



L

 * Unfortunately, the habit of praising or blaming without knowledge of the subject is becoming increasingly common to men of all parties today. This is not due to the failure of this or that doctrine, but to the crisis through which our whole civilisation is passing. At the same time this regrettable tendency adds greatly to the confusion in which all the sociological disputes of our day are taking place.

 * Strange, that ignorance should be our best happiness in this life, and yet be the one we are ever striving to destroy!
 * Letitia Elizabeth Landon, Heath's Book of Beauty, 1833, "The Enchantress"


 * Ignorance, far more than idleness, is the mother of all the vices; and how recent has been the admission, that knowledge should be the portion of all? The destinies of the future lie in judicious education; an education that must be universal, to be beneficial.
 * Letitia Elizabeth Landon, Ethel Churchill, Vol. 2, Chapter 31, 1837.


 * Never was there a greater need for the diffusion of knowledge, for in the present ignorance of men there is a very real and imminent danger. We have in the immediate future the possibility of serious struggle; we have all the elements of a possible social upheaval, and we have no religion with sufficient hold upon the people to check what may develop into a wild and dangerous movement. As yet philosophy is the study of the very few only, and the science which has done so much for us, and has achieved so many triumphs, cannot stay the danger which threatens us. The only thing that can prevent it is the diffusion of knowledge, so that men shall understand what is really best for them and shall realize that nothing can ever be good for one which is against the interests of the whole. p. 333

 * You can see how even the morals of a nation change. Hence, ignorance reacts to the pressure of the atmosphere. One must observe that ignorance clearly affirms the foundations of darkness.

 * It is my own peculiarity that I cannot bear ignorance, nor the ignorance of ignoramuses, and even less the ignorance of the informed.

 * Ignorance is degrading only when found in company with riches. The poor man is restrained by poverty and need: labour occupies his thoughts, and takes the place of knowledge. But rich men who are ignorant live for their lusts only, and are like the beasts of the field, as may be seen every day; and they can also be reproached for not having used wealth and leisure for that which gives them their greatest value.

 * [G]ame theory has already established itself as an essential tool in the, where it is widely regarded as a unifying language for investigating human behavior. Game theory's prominence in evolutionary biology builds a natural bridge between the life sciences and the behavioral sciences.

We live on a placid island of ignorance in the midst of black seas of infinity, and it was not meant that we should voyage far. The sciences, each straining in its own direction, have hitherto harmed us little; but some day the piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the light into the peace and safety of a new dark age.
