This model of thinking has become so entrenched in conventional academic wisdom that many educators accept it as canon".
The adoption of these principals parallels themselves with the increasing reliance on a quantitative understanding of the world.
Socrates established the fact that one cannot depend upon those in "authority" to have sound knowledge and insight.
He demonstrated that persons may have power and high position and yet be deeply confused and irrational.
Critical thinking employs not only logic but broad intellectual criteria such as clarity, credibility, accuracy, precision, relevance, depth, breadth, significance, and fairness.
The habits of mind that characterize a person strongly disposed toward critical thinking include a desire to follow reason and evidence wherever they may lead, a systematic approach to problem solving, inquisitiveness, even-handedness, and confidence in reasoning.In the ‘second wave’ of critical thinking, as defined by Kerry S. 1), many authors moved away from the logocentric mode of critical thinking that the ‘first wave’ privileged, especially in institutions of higher learning.Walters summarizes logicism as "the unwarranted assumption that good thinking is reducible to logical thinking".The ability to reason logically is a fundamental skill of rational agents, hence the study of the form of correct argumentation is relevant to the study of critical thinking."First wave" logical thinking consisted of understanding the connections between two concepts or points in thought.κριτικός = kritikos = "critic") derives from the word critic and implies a critique; it identifies the intellectual capacity and the means "of judging", "of judgement", "for judging", and of being "able to discern".2,500 years ago who discovered by a method of probing questioning that people could not rationally justify their confident claims to knowledge."A logistic approach to critical thinking conveys the message to students that thinking is legitimate only when it conforms to the procedures of informal (and, to a lesser extent, formal) logic and that the good thinker necessarily aims for styles of examination and appraisal that are analytical, abstract, universal, and objective." As the ‘second wave’ took hold, scholars began to take a more inclusive view of what constituted as critical thinking.Rationality and logic are still widely accepted in many circles as the primary examples of critical thinking. Walters (Re-thinking Reason, 1994) argues that rationality demands more than just logical or traditional methods of problem solving and analysis or what he calls the "calculus of justification" but also considers "cognitive acts such as imagination, conceptual creativity, intuition and insight" (p. These "functions" are focused on discovery, on more abstract processes instead of linear, rules-based approaches to problem-solving.The subject is complex, and several different definitions exist, which generally include the rational, skeptical, unbiased analysis, or evaluation of factual evidence.Critical thinking is self-directed, self-disciplined, self-monitored, and self-corrective thinking.
