Smith considered the teaching at Glasgow far superior to that at Oxford, which he found intellectually stifling.[9] In Book V, Chapter II of The Wealth of Nations, Smith wrote: "In the University of Oxford, the greater part of the public professors have, for these many years, given up altogether even the pretence of teaching." Smith is also reported to have complained to friends that Oxford officials once discovered him reading a copy of David Hume's Treatise on Human Nature, and they subsequently confiscated his book and punished him severely for reading it.[6][10][11] According to William Robert Scott, "The Oxford of [Smith's] time gave little if any help towards what was to be his lifework."[12] Nevertheless, Smith took the opportunity while at Oxford to teach himself several subjects by reading many books from the shelves of the large Oxford library.[13] When Smith was not studying on his own, his time at Oxford was not a happy one, according to his letters.[14] Near the end of his time at Oxford, Smith began suffering from shaking fits, probably the symptoms of a nervous breakdown.[15] He left Oxford University in 1746, before his scholarship ended.[15][16]
In Book V of The Wealth of Nations, Smith comments on the low quality of instruction and the meager intellectual activity at English universities, when compared to their Scottish counterparts. He attributes this both to the rich endowments of the colleges at Oxford and Cambridge, which made the income of professors independent of their ability to attract students, and to the fact that distinguished men of letters could make an even more comfortable living as ministers of the Church of England.[11]
