Philosophers frequently refer to the human mind, but what is meant by the mind is seldom made explicit, and when it is made explicit, it is confused, or simply wrong. My purpose here is to make explicit exactly what the mind is, and ultimately to make the important distinction between the mind and what is frequently and mistakenly included in that concept, the feelings and emotions.
Characteristics of Mind
Perception is the only kind of consciousness that any creature has, including human beings. The human mind is sometimes referred to as a unique kind of consciousness that only pertains to human beings. The mind is unique to human beings, but it is not a different kind of consciousness, since perception is the only kind of consciousness there is. [See the chapters, "Consciousness," and, "Perception."]
What is unique about human beings is not consciousness itself, but what human beings are consciously capable of doing. Only human beings are capable of conscious choice, which is called "volition," which makes possible and necessary the other attributes of what is called the human mind, "rationality," and, "intellect." These characteristics, volition, reason, and intellect, are interdependent capabilities which together are the human mind.
While it is consciousness that makes the human mind possible, the mind is not itself consciousness. Human consciousness, as far as we can tell, is not largely different from the consciousness of any of the higher animals: it is the conscious perception of physical reality and nothing more. Choosing, learning, and thinking are all done consciously, and are only possible to conscious beings, but consciousness itself is only awareness and does nothing itself.
Attributes of Mind
The mind may be identified by the following three attributes: volition, reason, and intellect.
Volition is the ability and necessity to consciously choose. All choice requires knowledge and the ability to answer questions and make judgments, which is, reasoning.
Reason is the ability to think, that is, to form and answer questions and make judgments. Reason requires volition and knowledge; volition, because a judgment is a choice; and knowledge, because knowledge is all there is to reason with or reason about.
Intellect is the ability to gain and store knowledge which is not possible without reason and volition; reason, to determine what is true (and therefore genuine knowledge), and volition to make the choice to think and learn.
These three, however, are not three different things, but three aspects of the same human faculty we call the human mind. Every thought we have is a volitional act, a conscious choice, and the manipulation of knowledge. Not everything that goes on in our consciousness is thinking, however. Much of our consciousness is occupied with feelings, imagination, and even "day dreams" which might or might not include thinking. Often the word mind is used to include these other aspects of our consciousness, or more correctly, of what we are conscious, but philosophers must not include them, because those kinds of things apparently occur in the consciousnesses of other creatures as well. Strictly speaking, what distinguishes humans from all other creatures is the unique mental function of thinking which is volitional, rational, and intellectual—that is, choosing to reason with and about what is known.
These three aspects of the mind need to be more fully explained, while emphasizing these are not independent attributes, and each requires and determines the others.
The human mind is sometimes referred to as "volitional consciousness," because the essential attribute of human nature that distinguishes it from all other animal natures is volition, and is the one that makes the other attributes possible and necessary.
Conscious choice, for human beings, is not only possible, but necessary. A human being cannot do anything, that can be chosen, without consciously choosing to do it. Of course, this does not include the involuntary actions such as reflexes or normal biological functions of the autonomic nervous system which are not chosen. Without choosing, a human being cannot do anything we consider human action from thinking, to eating a meal, to writing a computer program.
Some human action can be habitualized, of course, and it seems that we do such things as walking, driving a car, or typing without conscious choice, but such actions are also under our volitional control and can be altered or stopped at any time by choice, and the original learning of such habituated behavior had to be chosen.
Of the three aspects of the human mind, volition is the fundamental attribute, and exists as a faculty from the beginning of consciousness. All knowledge has to be acquired and the ability to reason, which is really the volitional use of knowledge, must be learned and developed.
The ability to reason is called "rationality," and since choices are made by means of reason, the human mind is also sometime referred to as "rational/volitional" consciousness.
A choice assumes knowledge—at a minimum, knowledge of what there is to choose and knowledge of which choices are preferable, which also means knowing what the consequences of choices will be. Determining which choice is preferable requires a judgment, an answer to certain questions, such as, "what is possible here?" "what will happen if I choose this?" and "which of these results is the best?" The process requires both the forming of the questions and determining the answers to the questions in relation to that kind of knowledge we call values. The answer to such questions is called a "judgment," because it makes an assessment (judgment) of what is preferable in terms of our values and the consequences of the chosen action or inaction.
Choices cannot be made without a process of reason, but there is no guarantee that one's reasoning will be correct. What is guaranteed is that a failure to reason correctly will certainly result in disastrous choices. If one allows desires, whims, or feelings, or any other kind of irrationality, to determine choices, the consequences of such choices are certain to be undesirable, disappointing, and harmful.
The formalization of the principles of correct reason is called logic. Unfortunately, there is a great deal that goes by the name logic today which has nothing to do with correct reasoning, and is frequently inimical to it. (Logical positivism, for example, or lately so-called "critical thinking," are examples.)
The word "knowledge" is used loosely to refer to many things which are not included in the meaning of the word in the philosophical sense, that is, intellectual knowledge. Intellectual knowledge requires language and is acquired and retained by means of words, which are abstract symbols for concepts or ideas.
The nature of knowledge and how it is acquired is the subject of the philosophical field of epistemology, which, of course, is the subject of this entire book.
Without knowledge there is no mind. It is what we know that all our reasoning is about, and all correct reasoning depends on knowledge. No thinking or choice is possible without knowledge, and the only limits to our thinking and choices is the limit of our knowledge.
The Mind, Consciousness, and Choice
Though the mind is not consciousness, all operations of the mind, learning, thinking, and choosing, are performed consciously and deliberately. Learning is deliberately forming memories of concepts and propositions. Thinking is deliberately comparing concepts and propositions and making judgments concerning them. Choosing is deliberately learning, thinking, and directing overt action. It is consciousness that makes these deliberate actions possible and we are conscious of performing them all but it is not consciousness itself that performs them.
The only part of conscious perception that is not directly and automatically determined by what there is to perceive are those percepts that originate in memory, and are, therefore, the only conscious percepts which can be chosen. Since all action is prompted (not determined) by whatever is in consciousness, the prompting itself, like the emotions, is determined directly by the content of consciousness. What prompted actions will be allowed must be consciously chosen. [See the section, "Consciousness Not Action," in the chapter, "Consciousness."]
How the choosing is performed is not known, anymore than it is known how we are conscious, but we know we are conscious because we are, and we know we choose, because we do, and we do it consciously, because what we are conscious of is all there is to choose from.
The kind of actions that are prompted by the content of consciousness include any kind of action, psychological or physical: recalling more perceptual content from memory, comparing concepts or propositions, making judgments, deliberately remembering a concept or proposition, or initiating an overt action. All these actions are occurring continuously and extremely rapidly, and we are conscious of them all. Though we cannot know the actual living function by which a choice is performed, we can say the mind is that aspect of our nature, as conscious beings, by which all action is chosen; that all deliberate remembering of concepts and propositions are chosen (learning), all deliberate judgments concerning comparing of concepts and propositions are chosen (thinking) and all decisions to do these things as well as initiating any overt actions are chosen (volition). [See the section, "Mind Versus Instinct Not a Perceptual Difference," in the, "Evolution," chapter.]
What Mind Is Not
Feelings, which include our emotions and desires, are not aspects of the mind. Our conscious identification of them is knowledge, because those identifications are concepts, but what we are conscious of as feelings is awareness of physical states.
All feelings and desires are physiological; that is, what is being "felt" are physiological states of the body. Many things can cause feelings including one's state of fatigue, infections and reactions to them, drugs, and hormones, for example, which all have physiological causes. Others are reactions to the content of consciousness, like fear (on seeing something frightening) or anger (on experiencing, or even thinking about, an injustice). Only those feelings that arise from the intellectual content of consciousness, that is, the mind, may properly be called emotions. Only those feelings which are the result of our thoughts, our knowledge, our principles and values are truly human emotions.
While animals seem to exhibit some emotions that seem akin to human emotions, like affection and fear, whatever animals actually feel, it is not quite the same as the human emotions which are evoked by their intellectual awareness. A dog might display affection for its master, but only a human can feel affection for someone by merely thinking about them, even when they are not present. A cat might be frightened by a loud noise, but only a human being will feel fear about something that has not yet happened, like a pending visit to the dentist.
Most emotions are uniquely human, depending entirely on the mind, or intellect, for their existence. Only human beings have feelings we describe as guilt or shame, pride, sadness or grief, humor, hate, and love. All of these are evoked by what we value, what we believe to be true, and what we think.
What thoughts or knowledge are associated with specific emotions is not always clear and must be learned, and is itself a kind of knowledge—knowledge of the relationships between our feelings and our thinking. We are familiar with many of those relationships.
If we do something we believe is wrong, the accompanying feeling is called guilt or shame. When we have accomplished something we believe is good and deserves to be recognized as such, the accompanying feeling we call pride. Learning of someone's death, especially a loved one, will be accompanied by the feelings we call sadness or grief. When made conscious of something we regard as outrageous or ironic, frequently the accompanying feeling is humor. When thinking about something we regard as evil, or dangerous, or loathsome, the accompanying feeling is called anger or hate. When we think about someone we value highly, someone important to us in every way, someone for whom we would willingly do anything to please, the accompanying feeling is called love.
[NOTE: In the case of love, it is the valuing of another that is the love, the feeling is not the love, it only accompanies it. When illness or any other physiological problem limits feelings, even of love, we do not love any less because we do not "feel" as loving.]
For some emotions, the fact that the feelings are physiological reactions is quite apparent, such as blushing when conscious of shame; smiling or laughing in reaction to something we regard as humorous; or tears and crying when thinking about what is sad. Many, perhaps most, of our emotions are much more subtle, however, with little or no externally observable reaction. For all these, for example, we know the feeling that accompanies the thought of them, and usually mean by them, both the thought and the feelings: hope, discouragement, anticipation, worry and anxiety, nostalgia, inspiration, enthusiasm (verses just excitement), seriousness or gravity, silliness or lightness, moral rectitude or self-esteem, frustration, victory, disappointment, self-assurance (competence, self-sufficiency), insecurity, and poise.
Not everything we think will be accompanied by any discernible feeling, though there is probably some physiological reaction, however slight, to every thought we have. Notice, however, that when there is a feeling, there must first be the thought the feeling is a reaction to. We do not feel grief until after we learn the loved one as passed away. We do not feel anxiety unless we are actually worrying about something. Also notice, that a change in what we think will change our feelings. We might be enjoying the pleasure of serious contemplation when a thought of something quite silly completely changes our feeling. We call such changes a change of mood.
The more subtle feelings can be deceptive, because they just seem to be there, innate, causeless, and vague. It is easy to make the mistake of thinking our feelings as just being in consciousness, or even a part of consciousness, rather than something we are conscious of.
In our every day language we frequently refer to what we feel, such as, "I feel this is a very grave situation," but what we mean is "I think this is a very grave situation," because a feeling of gravity or seriousness accompanies such thoughts; unfortunately, this is not always the case, and people will express what they feel about something, believing it is their feeling that is informing their belief, such as, "I just feel I ought to do that," having no idea why they have the feeling, which is a very dangerous mistake.
Summarizing: The human mind consists of the three interdependent aspects of the human consciousness we call volition, rationality, and intellect. The emotions are our consciousness of the physiological reactions of our bodies to the intellectual content of our consciousness, that is, our minds. Though our feelings are determined by the mind, and we are conscious of them, they are not part of the mind, and are non-cognitive; that is, they provide no information about anything beyond the feelings themselves. Decisions or choices influenced by feelings, which are not fully determined by reason, are irrational, and almost certain to be wrong.
[NOTE: Please see the chapters "Feelings," and, "Desires," for a fuller discussion of the emotional nature. Since the human mind is what makes knowledge and reason possible, all of epistemology is essentially a description of the mind, and the most important aspect of which is knowledge. Knowledge is all there is to think about or think with, and all choices must be made in the context of one's knowledge. Knowledge determines the scope of an individual's reason and the limit of one's choices, and therefore, one's life.]
