While I agree with my colleagues, I might add a bit glued together from Rand’s essay “The Objectivist Ethics” (this is pieced together, you have to supply the page numbers and ellipses).
What is morality, or ethics? It is a code of values to guide man’s choices and actions–the choices and actions that determine the purpose and the course of his life. The first question that has to be answered, as a precondition of any attempt to define, to judge or to accept any specific system of ethics, is: Why does man need a code of values? Is the concept of value, of “good or evil” an arbitrary human invention, unrelated to, underived from and unsupported by any facts of reality–or is it based on a metaphysical fact, on an unalterable condition of man’s existence?
In ethics, one must begin by asking: What are values? Why does man need them? “Value” is that which one acts to gain and/or keep. The concept “value” is not a primary; it presupposes an answer to the question: of value to whom and for what? It presupposes an entity capable of acting to achieve a goal in the face of an alternative. Where no alternative exists, no goals and no values are possible.
Only a living entity can have goals or can originate them. And it is only a living organism that has the capacity for self-generated, goal-directed action. An organism’s life depends on two factors: the material or fuel which it needs from the outside, from its physical background, and the action of its own body, the action of using that fuel properly. What standard determines what is proper in this context? The standard is the organism’s life, or: that which is required for the organism’s survival.
No choice is open to an organism in this issue: that which is required for its survival is determined by its nature, by the kind of entity it is. The goal of that action, the ultimate value which, to be kept, must be gained through its every moment, is the organism’s life. An ultimate value is that final goal or end to which all lesser goals are the means –and it sets the standard by which all lesser goals are evaluated. An organism’s life is its standard of value: that which furthers its life is the good, that which threatens it is the evil.
The pleasure-pain mechanism in the body of man– and in the bodies of all the living organisms that possess the faculty of consciousness –serves as an automatic guardian of the organism’s life. The physical sensation of pleasure is a signal indicating that the organism is pursuing the right course of action. The physical sensation of pain is a warning signal of danger, indicating that the organism is pursuing the wrong course of action, that something is impairing the proper function of its body, which requires action to correct it.
The simpler organisms, such as plants, can survive by means of their automatic physical functions. The higher organisms, such as animals and man, cannot: their needs are more complex and the range of their actions is wider. The physical functions of their bodies can perform automatically only the task of using fuel, but cannot obtain that fuel. To obtain it, the higher organisms need the faculty of consciousness. A plant can obtain its food from the soil in which it grows. An animal has to hunt for it. Man has to produce it.
The range of actions required for the survival of the higher organisms is wider: it is proportionate to the range of their consciousness. The higher organisms possess a much more potent form of consciousness: they possess the faculty of _retaining sensa_tions, which is the faculty of perception. Man has no automatic code of survival. He has no automatic course of action, no automatic set of values. His senses do not tell him automatically what is good for him or evil, what will benefit his life or endanger it, what goals he should pursue and what means will achieve them, what values his life depends on, what course of action it requires. His own consciousness has to discover the answers to all these questions-but his consciousness will not function automatically. Man, the highest living species on this earth–the being whose consciousness has a limitless capacity for gaining knowledge–man is the only living entity born without any guarantee of remaining conscious at all. Man’s particular distinction from all other living species is the fact that his consciousness is volitional.
The faculty that directs this process, the faculty that works by means of concepts, is: reason. The process is thinking. Consciousness–for those living organisms which possess it–is the basic means of survival. For man, the basic means of survival is reason. Man cannot survive, as animals do, by the guidance of mere percepts. A sensation of hunger will tell him that he needs food (if he has learned to identify it as “hunger”), but it will not tell him how to obtain his food and it will not tell him what food is good for him or poisonous.
