J.L. Mackie: The Subjectivity of Values (Part 4)
| [Part1] | [Part2] | [Part3] | [Part4] | [Part5] |
First, we must ponder the exact notion of value. With no need to assert psychological egoism, we can say that all human action is disposed toward the pursuit of value (subjective or objective), whether it is in seeking worldly pleasures, peace of mind, good conscience, or a healthy soul, and whether these actions are self- or other-oriented. Consider value as a means by which things can be preferred over others; in essence, how an agent values something will affect how he acts in order to attain or keep it. The objectivity of such values arises from the fact that agents, specifically humans, possess a physical nature that generates the material basis for a standard of evaluation, from which “the good” is generated. The presence of the fundamental alternatives of existence or nonexistence (“to be or not to be”) is a necessary precursor of value for humans. [1] Without some fundamental alternative, an agent’s course of action would have no purpose and thus no value, if he would even act at all.
Value, then, is derived from a system of conditional imperatives that reduce to the fundamental alternatives and the respective facts pertaining to them. If one wants to live, he ought to eat; if one wants to eat, he ought to produce food; if one wants to produce food, he ought to learn about agriculture, gathering, or hunting, etc. Because the achievement of prolonged existence or one of its corollaries is the achievement of a material state, there is a consistent and empirically-derived basis for resolving the content of the latter portion of conditional imperatives. In this sense, values are objective; they can not be achieved consistently by arbitrary whim.
Without any further elaboration, Mackie’s argument from relativity will pose a problem for the objectivity of value. One could simply argue that there was never a contention in the first place that the optimal fulfillment of hypothetical imperatives was not a matter of objective fact- that it is only the content of the “if” portions of the imperatives that lend themselves to subjectivity, and this is our concern. The problem with this assertion is that it ignores the essential commonality among human beings. In one way, relativity has merit: if you want to grow food in Italy, grow wheat; if you want to grow food in Ireland, grow potatoes. These are two different “ways” of life, both of which can be correct. However, those statements are merely higher-order expressions of the basic imperative, “if you want to live, eat,” which is one of the many imperatives relating to the agent’s relationship to the fundamental outcomes of existence versus non-existence. In other words, by their being what they are, humans are committed to the conditional imperative “if you are human, and if you want to live, satisfy your physical needs. ”[2] The chief difference between a condition such as “if you desire a grade of ‘A’” and “if you are human” is that the products of the latter have claim to objectivity, because the agent does not choose it, whether as an end or a means to an end; it is only a fact given by nature. The result is the existence of an objective value which is not intrinsic, but is logically dependent on the presence of humankind.
In the end, Mackie’s argument for the subjectivity of values makes a strong case against the existence of intrinsic values. He draws attention to several important inconsistencies and difficulties encountered by the philosophical daydreams of Platonic ideals, intrinsic values, and others of their conceptual family. Nevertheless, his argument is insufficient as proof for the subjectivity of values across different agents of the same kind (humans, as the only relevant case).
