Unlearn Quotes (11 quotes)

Can we ring the bells backward? Can we unlearn the arts that pretend to civilize, and then burn the world? There is a march of science; but who shall beat the drums for its retreat?

Every so often, you have to unlearn what you thought you already knew, and replace it by something more subtle.
With co-author Jack Cohen. In Terry Pratchett, Ian Stewart and Jack Cohen, Chap. 4, 'Science and Magic', The Science of Discworld (Rev. Ed. 2002), 14.

Following each, relevant real science is provided by his co-authors, Stewart and Cohen, in the even-numbered chapters (such as Chap. 4), but which of the two wrote which lines, is not designated.

Every student who enters upon a scientific pursuit, especially if at a somewhat advanced period of life, will find not only that he has much to learn, but much also to unlearn.

It is almost as difficult to make a man unlearn his errors, as his knowledge. Mal-information is more hopeless than non-information: for error is always more busy than ignorance. Ignorance is a blank sheet on which we may write; but error is a scribbled one on which we first erase. Ignorance is contented to stand still with her back to the truth; but error is more presumptuous, and proceeds, in the same direction. Ignorance has no light, but error follows a false one. The consequence is, that error, when she retraces her footsteps, has farther to go, before we can arrive at the truth, than ignorance.
Reflection 1, in Lacon: or Many things in Few Words; Addressed to Those Who Think (1820), 15.

It is characteristic of the unlearned that they are forever proposing something which is old, and because it has recently come to their own attention, supposing it to be new.
Address at Holy Cross College (25 Jun 1919), collected in Have Faith In Massachusetts: A Collection of Speeches and Messages (1919, 2nd Ed.), 231. (This speech was not included in the period covered by the first edition.)

To stay young requires unceasing cultivation of the ability to unlearn old falsehoods.
In Time Enough For Love: the Lives of Lazarus Long (1973), 364.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
