critical thinking: Self-directed, self-disciplined, self-monitored, and self-corrective thinking. It presupposes assent to rigorous standards of excellence and mindful command of their use. It entails effective communication and problem-solving abilities and a commitment to overcome our native egocentrism and sociocentrism. Everybody thinks; it is our nature to do so. But much of our thinking, left to itself, is biased, distorted, partial, uninformed, or down-right prejudiced. Shoddy thinking is costly, both in money and in quality of life. Excellence in thought through critical thinking must be systematically cultivated. A well-cultivated critical thinker: raises vital questions and problems, formulating them clearly and precisely; gathers and assesses relevant information, using abstract ideas to interpret it effectively; comes to well-reasoned conclusions and solutions, testing them against relevant criteria and standards; thinks open-mindedly within alternative systems of thought, recognizing and assessing, as need be, their assumptions, implications, and consequences; and communicates effectively with others in figuring out solutions to complex problems.
cultural assumption: An unassessed (often implicit) belief adopted by virtue of enculturation. Raised in a society, we unconsciously take on its point of view, values, beliefs, and practices. At the root of each of these are many assumptions. Not knowing that we perceive, conceive, think, and experience within assumptions we have taken in, we take ourselves to be perceiving things as they are, not things as they appear from a cultural vantage point. Becoming aware of our cultural assumptions so that we critically examine them is a crucial dimension of critical thinking.
data: Facts, figures, and information from which conclusions can be inferred, or upon which interpretations or theories can be based. As critical thinkers, we must make certain to distinguish hard data from the inferences or conclusions we draw from them.
egocentricity: A tendency to view everything in relationship to oneself; to confuse immediate perception (how things seem) with reality; the tendency to be self-centered or to consider only oneself and ones own interests; selfishness. Ones desires, values, and beliefs (seeming to be self-evidently correct, or superior to those of others) are often uncritically used as the norm of all judgment and experience. Egocentricity is one of the fundamental impediments to critical thinking. As one learns to think critically, one learns to become more rational, and less egocentric.
ethnocentricity: A tendency to view ones own race or culture as privileged, based on the deep-seated belief that ones own group is superior to all others. Ethnocentrism is a form of egocentrism extended from the self to the group. Much uncritical or selfish critical thinking is either egocentric or ethnocentric in nature. (Ethnocentrism and sociocentrism are used synonymously, for the most part, though sociocentricity is broader, relating to any social group, including, for example, sociocentrism regarding ones profession.) The cure for ethnocentrism or sociocentrism is empathic thought within the perspective of opposing groups and cultures. Such empathic thought is rarely cultivated. Instead, many give mere lip service to tolerance, but privileging the beliefs, norms, and practices of their own culture. Critical thinkers do not assume that the groups to which they belong are inherently superior to other groups. Instead, they attempt to accurately critique every viewpoint, seeking to determine its strengths and weaknesses. Their loyalty to a country is based on the principles and ideals of the country and not on uncritical loyalty to person, party, or national traditions.
fair-mindedness: A cultivated disposition of mind that enables the thinker to treat all perspectives relevant to an issue in an objective manner. It implies having a consciousness of the need to treat all viewpoints alike, without reference to ones own feelings or selfish interests, or the feelings or selfish interests of ones friends, community, or nation. It implies adherence to intellectual standards without reference to ones own advantage or the advantage of ones group.
human nature: The common qualities of all human beings. People have both a primary and a secondary nature. Our primary nature is spontaneous, egocentric, and strongly prone to the formation of irrational beliefs...the basis for our instinctual thought. People need no training to believe what they want to believe: what serves their immediate interests, what preserves their sense of personal comfort and righteousness, what minimizes their sense of inconsistency, and what presupposes their own correctness. People need no special training to believe what those around them believe: what their parents and friends believe, what is taught to them by religious and school authorities, what is repeated often by the media, and what is commonly believed in the nation in which they are raised. People need no training to think that those who disagree with them are wrong and probably prejudiced. People need no training to assume that their own most fundamental beliefs are self-evidently true or easily justified by evidence. People naturally and spontaneously identify with their own beliefs. They experience most disagreements as personal attacks. The resulting defensiveness interferes with their capacity to empathize with or enter into other points of view.
People need extensive and systematic practice to develop their secondary nature, their implicit capacity to function as rational persons. They need extensive and systematic practice to recognize the tendencies they have to form irrational beliefs. They need extensive practice to develop a dislike of inconsistency, an affinity for clarity, a passion to seek reasons and evidence and to be fair to points of view other than their own. People need extensive practice to recognize that they indeed have a point of view, that they live inferentially, that they do not have a direct pipeline to reality, that it is possible to have an overwhelming inner sense of the correctness of ones views and still be wrong.
intellectual autonomy: Having rational control of ones beliefs, values, and inferences. The ideal of critical thinking is to learn to think for oneself, to gain command over ones thought processes. Intellectual autonomy does not entail willfulness, stubbornness, or rebellion. It entails a commitment to analyzing and evaluating beliefs on the basis of reason and evidence, to question when it is rational to question, to believe when it is rational to believe, and to conform when it is rational to conform.
intellectual confidence or faith in reason: Assurance that in the long run ones own higher interests and those of humankind will best be served by giving the freest play to reasonby encouraging people to come to their own conclusions through a process of developing their own rational faculties; faith that (with proper encouragement and cultivation) people can learn to think for themselves, form rational viewpoints, draw reasonable conclusions, think coherently and logically, persuade each other by reason, and become reasonable, despite the deep-seated obstacles in the native character of the human mind and in society. Confidence in reason is developed through experiences in which one reasons ones way to insight, solves problems through reason, uses reason to persuade, is persuaded by reason. Confidence in reason is undermined when one is expected to accept beliefs on the sole basis of authority or social pressure.
intellectual courage: The willingness to face and fairly assess ideas, beliefs, or viewpoints to which we have not given a serious hearing, regardless of our strong negative reactions to them. This courage arises from the recognition that ideas considered dangerous or absurd are sometimes rationally justified (in whole or in part), and that conclusions or beliefs espoused by those around us or inculcated in us are sometimes false or misleading. To determine for ourselves which is which, we must not passively and uncritically accept what we have learned. Intellectual courage comes into play here, because inevitably we will come to see some truth in certain ideas considered dangerous and absurd and some distortion or falsity in certain ideas strongly held in our social group. It takes courage to be true to our own thinking in such circumstances. Examining cherished beliefs is difficult, and the penalties for nonconformity are often severe.
