The Diagnostic Society of Edinburgh is a debating society in Edinburgh, Scotland. The Diagnostic Society was founded in 1816 and traces its history back to the foundation of the Dialectic Society of Edinburgh in 1787, the two societies merging sometime in the 1960s, thus it claims to be the oldest debating society in UK. [1] Each meeting is lit by candlelight. [2]
The Diagnostics Society of Edinburgh was granted an official coat of arms in 1974, the only other student society to do so being the Cambridge Union Society.
Little is known about the Diagnostic Society, its records being held by University of Edinburgh.
