The intellectual roots of critical thinking date back to the Greek philosophers.

Socrates discovered, by means of probing questions, that in the exchange of competing ideas, people sometimes make confident claims based on unreliable assumptions or failed logic.

Such arguments, he discovered, were either erroneous in fact, absent sufficient foundation, or failing in logic. Instead, most arguments were based on confused meanings, inadequate evidence, or contradictory beliefs.

Socrates' contributions to critical thinking were many -- for he established new ways to think about contentious issues in terms of the quality of assumptions, facts and logic.

Thus Socrates demonstrated that persons may have passion, or power or high position but yet be deeply confused and irrational.

Good journalism, like compelling debate, is based on a clear understanding of facts and the logical construction of one's argument. And that is what the Socratic Method and The Sophist Tradition is all about.

Evidentiary Approach

The Socratic Method is the preferred way to examine issues.

In the Socratic mode of questioning, postulations, ideas or arguments are examined for their clarity and logical consistency by systematic analysis of facts, assumptions and logical methodology to support a conclusion.

Socratic analysis is accomplished by means of a series of probing questions that systematically examine the quality of an argument or conclusion.

Understanding the quality of information, argument or one's conclusions, is fundamental to critical thinking -- and the goal of critical editing.

Historical Foundation

Socrates’ practice was followed by the critical thinking of Plato (who recorded Socrates’ thought), Aristotle, and the Greek skeptics, all of whom emphasized that things are often very different from what they appear to be.

Only the trained mind is prepared to see through the way things look to us on the surface (delusive appearances) to the way they really are beneath the surface (the deeper realities of life.)

From this ancient Greek tradition emerged the need, for anyone who aspired to understand the deeper realities, to think systematically, to trace implications broadly and deeply; for only thinking that is comprehensive, well-reasoned, and responsive to objections can take us beyond the surface.

Means Of Analysis

The common denominators of Critical Thinking requires, for example, the systematic monitoring of thought; that thinking, to be critical, must not be accepted at face value, but must be analyzed and assessed for its clarity, accuracy, relevance, depth, breadth, and logical validity. All reasoning occurs within points of view and frames of reference.

All reasoning proceeds from some goals, objectives, and has an informational base. All data, when used in reasoning, must be interpreted. That interpretation involves concepts, that concepts entail assumptions, and that all basic inferences in thought have implications, and each of these dimensions of thinking need to be monitored where problems of thinking can occur.

Questioning Chain

The result of the collective contribution of the history of critical thought is that the basic questions of Socrates can now be much more powerfully and focally framed.

In every domain of human thought, and within every use of reasoning within any domain, it is now possible to question:

• ends and objectives
• the status and wording of questions
• the sources of information and fact
• the method and quality of information collection
• the mode of judgment and reasoning used
• the concepts that make that reasoning possible
• the assumptions that underlie concepts in use
• the implications that follow from their use
• the point of view or frame of reference within which reasoning takes place
