The Problem of Proper Names
A proper name tells us which thing is in question, without giving us any other information about it. But how does it do this? What exactly is the nature of this information? There are two puzzles in particular:
- The name in some way reveals the identity of the object. An identity statement, such as "Hesperus = Phosphorus" should contain no information at all. If we understand the names, we should understand the information they carry, namely the identity of their bearers, and if we grasp their identity, we should understand automatically whether the statement is true or false. Thus the statement should not be informative. Yet it is. The discovery that Hesperus = Phosphorus was (in its day) a great scientific achievement.
- Empty names have to seem perfectly meaningful. Then whose identity do they reveal? If the only semantic function of a name is to tell us which individual a proposition is about, how can it tell us this when there is no such individual?

Famous quotes containing the words problem, proper and/or names:
“Like the effects of industrial pollution ... the AIDS crisis is evidence of a world in which nothing important is regional, local, limited; in which everything that can circulate does, and every problem is, or is destined to become, worldwide.”
—Susan Sontag (b. 1933)
“We were hospitably entertained in Concord, New Hampshire, which we persisted in calling New Concord, as we had been wont, to distinguish it from our native town, from which we had been told that it was named and in part originally settled. This would have been the proper place to conclude our voyage, uniting Concord with Concord by these meandering rivers, but our boat was moored some miles below its port.”
—Henry David Thoreau (1817–1862)
“Consider the islands bearing the names of all the saints, bristling with forts like chestnut-burs, or Echinidæ, yet the police will not let a couple of Irishmen have a private sparring- match on one of them, as it is a government monopoly; all the great seaports are in a boxing attitude, and you must sail prudently between two tiers of stony knuckles before you come to feel the warmth of their breasts.”
—Henry David Thoreau (1817–1862)
