John Gilbert Cooper (1723-1769)
From 18th Century Literary Anecdotes

Mr. GILBERT COOPER was the last of the benevolists, or sentimentalists, who were much in vogue between 1750 and 1760, and dealt in general admiration of virtue. They were all tenderness in words; their inner feelings evaporated in the moment of expression, for they had no connection with their practice. He was the person whom, when lamenting most piteously that his son then absent might be ill or even dead, Mr. Fitzherbert so grievously disconcerted by saying, in a growling tone, 'Can't you take a postchaise, and go and see him?'
