The greatest happiness of my time at Cambridge was connected with a body whom its members knew as 'The Society', but which outsiders if they knew of it, called 'The Apostles'. This was a small discussion society, containing one or two people from each year on the average, which met every Saturday night. It has existed since 1820, and has had as members most of the people of any intellectual eminence who have been at Cambridge since then. ... We discussed all manner of things, no doubt with a certain immaturity, but with a detachment and interest scarcely possible in later life.
