Practical knowledge of what works and what doesn't work is much better. Theoretical knowledge is important, but I think practical knowledge works better.
Opportunism towards knowledge is a utilitarian demand that knowledge must be immediately practical. Just like with sociology where we hope its purpose is to serve society, however, the true purpose of sociology lies in its impracticality. It cannot become practical or else it loses its meaning. Perhaps we should learn a different kind of knowledge: the knowledge to question knowledge.
I am aware of the technical distinction between ‘less’ and ‘fewer’, and between ‘uninterested’ and ‘disinterested’ and ‘infer’ and ‘imply’, but none of these are of importance to me. ‘None of these are of importance,’ I wrote there, you’ll notice – the old pedantic me would have insisted on “none of them is of importance”. Well I’m glad to say I’ve outgrown that silly approach to language
Don't rely on logic alone, nor speculation. Don't infer or be deceived by appearances.
Among all the liberal arts, the first is logic, and specifically that part of logic which gives initial instruction about words. ... [T]he word "logic" has a broad meaning, and is not restricted exclusively to the science of argumentative reasoning. [It includes] Grammar [which] is "the science of speaking and writing correctly-the starting point of all liberal studies."
Don't imagine that you'll discover {the truth} by accumulating more knowledge. Knowledge creates doubt, and doubt makes you ravenous for more knowledge. You can't get full eating this way.
Knowledge and personality make doubt possible, but knowledge is also the cure of doubt; and when we get a full and adequate sense of personality we are lifted into a region where doubt is almost impossible, for no man can know himself as he is, and all fullness of his nature, without also knowing God.
If you think about the practical difficulties of having a relationship with somebody on the other side of the world, it defies all logic.
Logic is an excellent weapon when employed correctly.
After all, what was the whole wide world but a place for people to yearn for their heart's impossible desires, for those desires to become entrenched in defiance of logic, plausibility, and even the passage of time, as eternal as polished marble.
An accurate knowledge of the past of a country is necessary for everyone who would understand its present, and who desires to judge of its future.
Doubt is a profound and effective spiritual motivation. Without doubt, no truism is transcended, no new knowledge found, no expansion of the imagination possible. Doubt is unsettling to the ego and those who are drawn to ideologies that promise the dispelling of doubt by preferring certainties never grow.
There is a considerable amount of manipulation in the printmaking from the straight photograph to the finished print. If I do my job correctly that shouldn't be visible at all, it should be transparent.
It's true that the level of scientific knowledge among adults is very low, but that's not because there isn't a natural interest. I think most kids are fascinated by the natural world. I've often said that if you could quantify the mental power involved in all the dinosaur names correctly known and correctly spelled by 5-year-old kids in America, you could move any mountain on earth.
Gradually, ... the aspect of science as knowledge is being thrust into the background by the aspect of science as the power of manipulating nature. It is because science gives us the power of manipulating nature that it has more social importance than art. Science as the pursuit of truth is the equal, but not the superior, of art. Science as a technique, though it may have little intrinsic value, has a practical importance to which art cannot aspire.
It seems to us that in intelligence there is a fundamental faculty, the alteration or the lack of which, is of the utmost importance for practical life. This faculty is judgment, otherwise called good sense, practical sense, initiative, the faculty of adapting one's self to circumstances. A person may be a moron or an imbecile if he is lacking in judgment; but with good judgment he can never be either. Indeed the rest of the intellectual faculties seem of little importance in comparison with judgment.
