"I already mentioned that the standard skeptic, and humanist, answer to morality is evolutionary adaptation. But evolution does not give us objective morality, but rather explains why people hold the moral positions they do. It explains why the whim exists, but not what reality actually indicates. Evolutionary adaptations are based on a non-directed process, and are based on the human species and environment as it existed millions of years ago. Even if the evolutionary process was flawless from our perspective, it would hardly make the moral instincts of a tribal, status-based species living in an ancestral environment, devoid of almost all technology, applicable to today’s world.
We can say that the morality-as-evolutionary position is flawed precisely because it is subjective: it uses objective facts (evolution and evolutionary psychology) but uses them to falsely deduce moral facts. If there is to be knowledge about morality, then it must be objective, that is to say, based on Reason: beyond that, we must remain silent.
To claim that morality is subjective is a denial of causality – actions have consequences, which arise because of natural, psychological and social laws. If you stop eating, you will die. If you stop drinking water, you will die even faster. If you break the social mores of decency or peaceful behaviour in your relationships with others, your life will be affected and even endangered. If you do not pursue social values in general, you will live isolated from the benefits of civilization. If you do not pursue mental values, you will not have the mental capacity to reason our way through life. Without such values, you would easily fall prey to any received idea, any scam, you would have no capacity to manage your life. Causality is universal: actions have consequences, causes have effects, if we fail to follow the requirements of life we will fail to live.
Whatever the moral system upheld by the individual, we can express the general value-judgment process simply in the following manner:
1. There is a moral choice, with two or more possible actions.
2. Those actions exist in a context.
3. The combination of that context and our hierarchy of values (whatever its form) determines the values effected by each action.
We already have a hierarchical system of values in humanistic psychology, which is called Maslow’s Hierarchy of Needs, and is generally accepted in the field. David Kelley gives a similar account of human needs in “Logical Structure of Objectivism”, albeit one that also includes vital philosophical concerns (bold his):
” Material needs such as needs for health and food: these values contribute directly to survival.
Spiritual needs such as needs for conceptual knowledge, self-esteem, education and art: these values are spiritual in the sense that they primarily pertain to consciousness, and contribute to survival by helping Reason to function properly.
Social needs such as needs for trade, communication, friendship and love: these values are social in that they occur only through interaction with others. Logically, their status as values is due to the fact that they contribute to the fulfillment of spiritual and material needs.
Political needs such as needs for freedom and objective law, which are needs concerning the organization of society. These provide the context for fulfilling our material, spiritual and social needs”
(p81)
I think it is pretty clear that all of its parts are objective. They are based on existing physical and psychological causal facts that we observe in ourselves and other people. It is also a hierarchy, given that the needs at one level need to be fulfilled to a suitable extent before we can be concerned about the others.
A value is a goal that our actions seek to accomplish. Objective values have a one-to-one correspondence with objective needs, because needs indicate the goals that need to be fulfilled. As David Kelley judiciously writes in “Logical Structure of Objectivism” (italics his):
“The place of biological needs in the logical structure of Objectivism is this: since one’s life is one’s ultimate value, one has to know what one needs for the maintenance of life in order to know what to seek as a value.
The needs of a living organism determine its goals. In other words, its needs determine its values.”
(p69-70)
We have a hierarchy of values for the same reason than we have a hierarchy of needs – because some values need to be reasonably fulfilled (such as nutrition or sleep) before some others can come under the purview of our actions (such as love or excellence). There is a gradient of importances that necessarily enters into account here. That is why one may say, objectively, that eating is much more important than, say, gaining status. But these values are universal: they apply to all human beings, except in some cases where higher values cannot be effected due to physical defect.
It is important here to understand that while values themselves are objective in all ways, their specific implementation differs from person to person and from culture to culture. For instance, we all need to eat, but we do not eat the same things. Someone in Latvia might eat a dinner of bizugis with pea balls and a glass of maizes kvass, and I might have a piece of tourtière with maple syrup and a glass of milk. But it remains an inescapable biological fact that we both need to eat to survive.
Contextuality expresses the fact that an action does not exist in a vacuum. When we examine an action, we cannot ignore that the action takes place in a given context. This context is necessary to evaluate the consequences of an action, because it informs the values that are effected by the action."
