I try in my prints to testify that we live in a beautiful and orderly world, not in a chaos without norms, even though that is how it sometimes appears. My subjects are also often playful: I cannot refrain from demonstrating the nonsensicalness of some of what we take to be irrefutable certainties. It is, for example, a pleasure to deliberately mix together objects of two and three dimensions, surface and spatial relationships, and to make fun of gravity.
Samuel Johnson
It may be observed in general that the future is purchased by the present. It is not possible to secure distant or permanent happiness but by the forbearance of some immediate gratification. This is so evidently true with regard to the whole of our existence that all precepts of theology have no other tendency than to enforce a life of faith; a life regulated not by our senses but by our belief; a life in which pleasures are to be refused for fear of invisible punishments, and calamities sometimes to be sought, and always endured, in hope of rewards that shall be obtained in another state.
