Beauty, whether moral or natural, is felt, more properly than perceived.

Context

“It has a foundation in reason, so far as it is supported by experience. But its best and most solid foundation is faith and divine revelation. Morals and criticism are not so properly objects of the understanding as of taste and sentiment. Beauty, whether moral or natural, is felt, more properly than perceived. Or if we reason concerning it, and endeavour to fix its standard, we regard a new fact, to wit, the general tastes of mankind, or some such fact, which may be the object of reasoning and enquiry. When we run over libraries, persuaded of these principles, what havoc must we make?” source
