part of a car's definition, it would be given no weight. Headlights could be weighed twice, once or not at all depending on how headlights appear in the description of a car. Given a finite set of n properties, a thing is good if it is perceived to have all of the properties, fair if it has more than n/2 of them, average if n/2 of them, and bad if it has fewer than n/2. Infinite sets of properties Hartman goes on to consider infinite sets of properties. Hartman claims that according to a theorem of transfinite mathematics, any collection of material objects is at most denumerably infinite. This is not, in fact, a theorem of mathematics. But, according to Hartman, people are capable of a denumerably infinite set of predicates, intended in as many ways, which he gives as . As this yields a notional cardinality of the continuum, Hartman advises that when setting out to describe a person, a continuum of properties would be most fitting and appropriate to bear in mind. This is the cardinality of intrinsic value in Hartman's system. Although they play no role in ordinary mathematics, Hartman deploys the notion of aleph number reciprocals, as a sort of infinitesimal proportion. This, he contends goes to zero in the limit as the uncountable cardinals become larger. In Hartman's calculus, for example, the assurance in a Dear John letter, that "we will always be friends" has axiological value , whereas taking a metaphor literally would be slightly preferable, the reification having a value of . Evaluation of Hartman's work Hartman invented the Hartman Value Profile, which is however not a description of what is valuable, but a test to determine what people regard as valuable. It measures concept-formation and decision-making capacity. A Hartman festschrift (Values and Valuation) appeared a few years after his death. Some critics would claim that most of the articles in it are not by Hartman supporters. Hartman, some critics claim, is out of the mainstream of value philosophy, but he was asked by UNESCO to summarize the state of Value Theory at Mid-Century. Many would dispute the idea that the number of properties of a thing can in any meaningful way be enumerated, but this is something Hartman never said was necessary. A standard argument against enumeration is that new properties can be defined in terms of old ones. Adding more features,
