Two generations of enthusiasts produced the philosophical geniuses of the Scottish Enlightenment. The first generation created the climate of self-improvement emphasising tolerance and open-mindedness; a humanist climate. The second generation was born into and brought up in this atmosphere in which the best was expected of them. The first generation clubbed together to improve themselves and bring Scottish culture up to English standards of intellectual achievement. The first clubs were largely literary. With the Rankenian Club in 1717 onwards interest in philosophical discussions increased among the literari. Later clubs and societies such as the Select Society in Edinburgh and the Aberdeen Philosophical Society were dedicated to philosophical discus-sions and improving their writing and speaking skills in that subject.
