Richard Cumberland (philosopher) Quote
The art of being agreeable frequently miscarries through the ambition which accompanies it. Wit, learning, wisdom,--what can more effectually conduce to the profit and delight of society? Yet I am sensible that a man may be too invariably wise, learned, or witty to be agreeable; and I take the reason of this to be, that pleasure cannot be bestowed by the simple and unmixed exertion of any one faculty or accomplishment.
