Amusement is a much more directly physical thing. We may be amused without any idea at all, as when we are tickled, or laugh in sympathy with others by a contagious imitation of their gestures. We may be amused by the mere repetition of a thing at first not amusing.

Context

“The most conspicuous headings under which comic effects are gathered are perhaps incongruity and degradation. But clearly it cannot be the logical essence of incongruity or degradation that constitutes the comic; for then contradiction and deterioration would always amuse. Amusement is a much more directly physical thing. We may be amused without any idea at all, as when we are tickled, or laugh in sympathy with others by a contagious imitation of their gestures. We may be amused by the mere repetition of a thing at first not amusing. There must therefore be some nervous excitement on which the feeling of amusement directly depends, although this excitement may most often coincide with a sudden transition to an incongruous or meaner image.” source
