De finibus

A fixed-position box at the bottom of the viewport floats over this document. It displays three identical silent videos without using script. From left to right, they are WebM or AVC video, GIF, and JPEG filmstrip. To make the document long enough to flow under the box, I'll quote what M. T. Cicero wrote in 45 B.C.:

But I must explain to you how all this mistaken idea of denouncing pleasure and praising pain was born and I will give you a complete account of the system, and expound the actual teachings of the great explorer of the truth, the master-builder of human happiness. No one rejects, dislikes, or avoids pleasure itself, because it is pleasure, but because those who do not know how to pursue pleasure rationally encounter consequences that are extremely painful. Nor again is there anyone who loves or pursues or desires to obtain pain of itself, because it is pain, but because occasionally circumstances occur in which toil and pain can procure him some great pleasure. To take a trivial example, which of us ever undertakes laborious physical exercise, except to obtain some advantage from it? But who has any right to find fault with a man who chooses to enjoy a pleasure that has no annoying consequences, or one who avoids a pain that produces no resultant pleasure?

On the other hand, we denounce with righteous indignation and dislike men who are so beguiled and demoralized by the charms of pleasure of the moment, so blinded by desire, that they cannot foresee the pain and trouble that are bound to ensue; and equal blame belongs to those who fail in their duty through weakness of will, which is the same as saying through shrinking from toil and pain. These cases are perfectly simple and easy to distinguish. In a free hour, when our power of choice is untrammelled and when nothing prevents our being able to do what we like best, every pleasure is to be welcomed and every pain avoided. But in certain circumstances and owing to the claims of duty or the obligations of business it will frequently occur that pleasures have to be repudiated and annoyances accepted. The wise man therefore always holds in these matters to this principle of selection: he rejects pleasures to secure other greater pleasures, or else he endures pains to avoid worse pains.

The above is the English translation by H. Rackham of a passage from Cicero's philosophical treatise On the Ends of Good and Evil. Many type designers, typographers, and other designers use "Lorem ipsum", a somewhat corrupted version of Cicero's passage in the original Latin. I instead use English for two reasons. First, it helps clarify why people go through the pain of developing websites and web applications: it results in the pleasure of a finished product. Second, design serves the copy, not vice versa. Real and relevant copy makes the design more representative of the reader's experience throughout the process.
