The higher organisms possess a much more potent form of consciousness: they possess the faculty of retaining sensations, which is the faculty of perception. A “perception” is a group of sensations automatically retained and integrated by the brain of a living organism, which gives it the ability to be aware, not of single stimuli, but of entities, of things. An animal is guided, not merely by immediate sensations, but by percepts. Its actions are not single, discrete responses to single, separate stimuli, but are directed by an integrated awareness of the perceptual reality confronting it. It is able to grasp the perceptual concretes immediately present and it is able to form automatic perceptual associations, but it can go no further. It is able to learn certain skills to deal with specific situations, such as hunting or hiding, which the parents of the higher animals teach their young. But an animal has no choice in the knowledge and the skills that it acquires; it can only repeat them generation after generation. And an animal has no choice in the standard of value directing its actions: its senses provide it with an automatic code of values, an automatic knowledge of what is good for it or evil, what benefits or endangers its life. An animal has no power to extend its knowledge or to evade it. In situations for which its knowledge is inadequate, it perishes—as, for instance, an animal that stands paralyzed on the track of a railroad in the path of a speeding train. But so long as it lives, an animal acts on its knowledge, with automatic safety and no power of choice: it cannot suspend its own consciousness—it cannot choose not to perceive—it cannot evade its own perceptions—it cannot ignore its own good, it cannot decide to choose the evil and act as its own destroyer.
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.
Just as the automatic values directing the functions of a plant’s body are sufficient for its survival, but are not sufficient for an animal’s—so the automatic values provided by the sensory-perceptual mechanism of its consciousness are sufficient to guide an animal, but are not sufficient for man. Man’s actions and survival require the guidance of conceptual values derived from conceptual knowledge. But conceptual knowledge cannot be acquired automatically.
A “concept” is a mental integration of two or more perceptual concretes, which are isolated by a process of abstraction and united by means of a specific definition. Every word of man’s language, with the exception of proper names, denotes a concept, an abstraction that stands for an unlimited number of concretes of a specific kind. It is by organizing his perceptual material into concepts, and his concepts into wider and still wider concepts that man is able to grasp and retain, to identify and integrate an unlimited amount of knowledge, a knowledge extending beyond the immediate perceptions of any given, immediate moment. Man’s sense organs function automatically; man’s brain integrates his sense data into percepts automatically; but the process of integrating percepts into concepts—the process of abstraction and of concept-formation—is not automatic.
The process of concept-formation does not consist merely of grasping a few simple abstractions, such as “chair,” “table,” “hot,” “cold,” and of learning to speak. It consists of a method of using one’s consciousness, best designated by the term “conceptualizing.” It is not a passive state of registering random impressions. It is an actively sustained process of identifying one’s impressions in conceptual terms, of integrating every event and every observation into a conceptual context, of grasping relationships, differences, similarities in one’s perceptual material and of abstracting them into new concepts, of drawing inferences, of making deductions, of reaching conclusions, of asking new questions and discovering new answers and expanding one’s knowledge into an ever-growing sum. The faculty that directs this process, the faculty that works by means of concepts, is: reason. The process is thinking.
Reason is the faculty that identifies and integrates the material provided by man’s senses. It is a faculty that man has to exercise by choice. Thinking is not an automatic function. In any hour and issue of his life, man is free to think or to evade that effort. Thinking requires a state of full, focused awareness. The act of focusing one’s consciousness is volitional. Man can focus his mind to a full, active, purposefully directed awareness of reality—or he can unfocus it and let himself drift in a semiconscious daze, merely reacting to any chance stimulus of the immediate moment, at the mercy of his undirected sensory-perceptual mechanism and of any random, associational connections it might happen to make.
When man unfocuses his mind, he may be said to be conscious in a subhuman sense of the word, since he experiences sensations and perceptions. But in the sense of the word applicable to man—in the sense of a consciousness which is aware of reality and able to deal with it, a consciousness able to direct the actions and provide for the survival of a human being—an unfocused mind is not conscious.
Psychologically, the choice “to think or not” is the choice “to focus or not.” Existentially, the choice “to focus or not” is the choice “to be conscious or not.” Metaphysically, the choice “to be conscious or not” is the choice of life or death.
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. He cannot provide for his simplest physical needs without a process of thought. He needs a process of thought to discover how to plant and grow his food or how to make weapons for hunting. His percepts might lead him to a cave, if one is available—but to build the simplest shelter, he needs a process of thought. No percepts and no “instincts” will tell him how to light a fire, how to weave cloth, how to forge tools, how to make a wheel, how to make an airplane, how to perform an appendectomy, how to produce an electric light bulb or an electronic tube or a cyclotron or a box of matches. Yet his life depends on such knowledge—and only a volitional act of his consciousness, a process of thought, can provide it.
But man’s responsibility goes still further: a process of thought is not automatic nor “instinctive” nor involuntary—nor infallible. Man has to initiate it, to sustain it and to bear responsibility for its results. He has to discover how to tell what is true or false and how to correct his own errors; he has to discover how to validate his concepts, his conclusions, his knowledge; he has to discover the rules of thought, the laws of logic, to direct his thinking. Nature gives him no automatic guarantee of the efficacy of his mental effort.
Nothing is given to man on earth except a potential and the material on which to actualize it. The potential is a superlative machine: his consciousness; but it is a machine without a spark plug, a machine of which his own will has to be the spark plug, the self-starter and the driver; he has to discover how to use it and he has to keep it in constant action. The material is the whole of the universe, with no limits set to the knowledge he can acquire and to the enjoyment of life he can achieve. But everything he needs or desires has to be learned, discovered and produced by him—by his own choice, by his own effort, by his own mind.
A being who does not know automatically what is true or false, cannot know automatically what is right or wrong, what is good for him or evil. Yet he needs that knowledge in order to live. He is not exempt from the laws of reality, he is a specific organism of a specific nature that requires specific actions to sustain his life. He cannot achieve his survival by arbitrary means nor by random motions nor by blind urges nor by chance nor by whim. That which his survival requires is set by his nature and is not open to his choice. What is open to his choice is only whether he will discover it or not, whether he will choose the right goals and values or not. He is free to make the wrong choice, but not free to succeed with it. He is free to evade reality, he is free to unfocus his mind and stumble blindly down any road he pleases, but not free to avoid the abyss he refuses to see. Knowledge, for any conscious organism, is the means of survival; to a living consciousness, every “is” implies an “ought.” Man is free to choose not to be conscious, but not free to escape the penalty of unconsciousness: destruction. Man is the only living species that has the power to act as his own destroyer—and that is the way he has acted through most of his history.
