Quotes:

““When something quite new and singular is presented … The memory cannot, from all its stores, cast up any image that nearly resembles this strange appearance. It stands alone and by itself in the imagination. (This) constitute(s) the sentiment properly called Wonder, and occasion(s) that staring, and sometimes that rolling of the eyes, that suspension of the breath, and that swelling of the heart, which we may all observe, both in ourselves and others, when wondering at some new object.”

– Adam Smith on Wonder.
