A teacher can never truly teach unless he is still learning himself. A lamp can never light another lamp unless it continues to burn its own flame. The teacher who has come to the end of his subject, who has no living traffic with his knowledge but merely repeats his lesson to his students, can only load their minds, he cannot quicken them.
I think the average Jew is probably sharper intellectually than the average gentile, because for years and years he's had to live by his wits. Consequently, there has evolved a race of Jews who are more agile mentally than the rest of us.
If one adjusts for socioeconomic factors, it is the Asians who have the highest IQs in America, not the Jews.
The longer I have been an atheist, the more amazed I am that I ever believed Christian notions.
A foolish consistency is the hobgoblin of little minds, adored by little statesmen and philosophers and divines. With consistency a great soul has simply nothing to do. He may as well concern himself with his shadow on the wall. Speak what you think now in hard words and to-morrow speak what to-morrow thinks in hard words again, though it contradict every thing you said to-day.
Newton was not the first of the age of reason. He was the last of the magicians, the last of the Babylonians and Sumerians, the last great mind that looked out on the visible and intellectual world with the same eyes as those who began to build our intellectual inheritance rather less than 10,000 years ago.
What transforms this world is - knowledge. Do you see what I mean? Nothing else can change anything in this world. Knowledge alone is capable of transforming the world, while at the same time leaving it exactly as it is. When you look at the world with knowledge, you realize that things are unchangeable and at the same time are constantly being transformed.
It is paradoxical, yet true, to say, that the more we know, the more ignorant we become in the absolute sense, for it is only through enlightenment that we become conscious of our limitations. Precisely one of the most gratifying results of intellectual evolution is the continuous opening up of new and greater prospects.
Ideas improve. The meaning of words participates in the improvement. Plagiarism is necessary. Progress implies it. It embraces an author's phrase, makes use of his expressions, erases a false idea, and replaces it with the right idea.
We should be most careful about retreating from the specific challenge of our age. We should be reluctant to turn our back upon the frontier of this epoch... We cannot be indifferent to space, because the grand slow march of our intelligence has brought us, in our generation, to a point from which we can explore and understand and utilize it. To turn back now would be to deny our history, our capabilities.
The progress of the human race in understanding the universe has established a small corner of order in an increasingly disordered universe.
Some great minds become great by turning the rubble of an exploded paradigm into something consistent and meaningful. Others become great by laying the gunpowder, grain by grain. Every important revolution needs both kinds of minds to complete itself.
First... a new theory is attacked as absurd; then it is admitted to be true, but obvious and insignificant; finally it is seen to be so important that its adversaries claim that they themselves discovered it.
Some have narrowed their minds, and so fettered them with the chains of antiquity that not only do they refuse to speak save as the ancients spake, but they refuse to think save as the ancients thought. God speaks to us, too, and the best thoughts are those now being vouchsafed to us. We will excel the ancients!
Geniuses must never die, the progress of mankind depends on us
All the history of human life has been a struggle between wisdom and stupidity.
There comes a moment in history when ignorance is no longer a forgivable offense... a moment when only wisdom has the power to absolve. - Bertrand Zobrist
Ideas are invented only as correctives to the past. Through repeated rectification of this kind one may hope to disengage an idea that is valid.
Thus with every advance in our scientific knowledge new elements come up, often forcing us to recast our entire picture of physical reality. No doubt, theorists would much prefer to perfect and amend their theories rather than be obliged to scrap them continually. But this obligation is the condition and price of all scientific progress.
Those who are really convinced that they have made progress in science would not demand freedom for the new views to continue side by side with the old, but the substitution of the new views for the old.
The freethinking of one age is the common sense of the next.
Innovation is a twofold threat to academic mediocrities: it endangers their oracular authority, and it evokes the deeper fear that their whole, laboriously constructed intellectual edifice might collapse.
The first indication of a young person's growing smarter is that he no longer understands the things which he used to consider quite intelligible and self-evident.
Progress is the victory of a new thought over old superstitions.
You are an explorer, and you represent our species, and the greatest good you can do is to bring back a new idea, because our world is endangered by the absence of good ideas. Our world is in crisis because of the absence of consciousness.
... in the history of the human mind there has never been a useful thought or a profound truth that has not found its century and admirers.
