The name of a class should reflect its intrinsic nature and not a role that it plays in an association. For example, Owner would be a poor name for a class in a car manufacturer's database. What if a list of drivers is added later? What about persons who lease cars? The proper class is Person (or possibly Customer), which assumes various different roles, such as owner, driver, and lessee.

Reporter: How many people who labor in the same musical vineyard in which you toil - how many are protest singers? That is, people who use their music, and use the songs to protest the, uh, social state in which we live today: the matter of war, the matter of crime, or whatever it might be.
Bob Dylan: Uh, I think there's about, uh...136.
Reporter: You say about 136, or you mean exactly 136?
Bob Dylan: Uh, it's either 136 or 142.

Now, since the time of Newton there had been a debate about whether light was a wave---that is, a traveling disturbance in some background medium---or a particle, which travels regardless of the presence of a background medium. The observation of Maxwell that electromagnetic waves must exist and that their speed was identical to that of light ended the debate: light was an electromagnetic wave.
Lawrence M. Krauss
My poor soul! Sigh, pray and strive to take upon you the blessed yoke of Christ, and you will live on earth in a heavenly manner. Lord, grant that I may carry the light and goodly yoke, and I shall be always at rest, peaceful, glad and joyous; and I shall taste on earth of crumbs which fall from the celestial feast, like a dog that feeds upon the crumbs which fall from the master's table.
Tikhon of Zadonsk
Everywhere Christians are tempted to take the easy path, to seek "peace" and "security" and flee from pain and affliction, to view life as an occasion for the enjoyment of earthly blessings, instead of a time of trial in which our eternal destiny is to be decided. But God expects more than this from those who glory in the name of Orthodox Christians.

What will be the attitude of communism to existing nationalities? The nationalities of the peoples associating themselves in accordance with the principle of [[community will be compelled to mingle with each other as a result of this association and thereby to dissolve themselves, just as the various estate and class distinctions must disappear through the abolition of their basis, private property.
Friedrich Engels
