“The spread of secondary and later of tertiary education has created a large population of people, often with well-developed literary and scholarly tastes, who have been educated far beyond their capacity for anaytical thought.”
The above quote is a more modern version of the saying “A little knowledge is a dangerous thing”, despite the superficial contradiction. The first one is talking about information, while the second one is talking about that portion of information backed up by reason. A fundamental failing of modern education systems is that in it’s hurry to pile information on it’s victims it sidelines analytical thinking. By the time students finish high school, most of them stop seeing any deep significance in what they are learning because they are too busy focussing on the details…
Critical thinking and scepticism are faculties that should be cultivated early on in one’s life, failing which, all knowledge, no matter how little or big it is, becomes dangerous, as it merely serves to reinforce whatever fanciful delusions a person might have.
