3. Sumner's Definition of Critical Thinking
What is Critical Thinking?
(William Graham Sumner — 1906)
 “[Critical thinking is] . . . the examination and test of propositions of any kind
which are offered for acceptance, in order to find out whether they correspond
to reality or not. The critical faculty is a product of education and training. It is
a mental habit and power. It is a prime condition of human welfare that men and
women should be trained in it. It is our only guarantee against delusion,
deception, superstition, and misapprehension of ourselves and our earthly
circumstances.”


Usages, Manners, Customs, Mores, and Morals, New York: Ginn and Co., pp. 632,
633.}

6. Definitions
 Different sources define critical thinking variously as:
 "reasonable reflective thinking focused on deciding what to believe or do"[2]
 "the intellectually disciplined process of actively and skillfully conceptualizing, applying,
analyzing, synthesizing, or evaluating information gathered from, or generated by,
observation, experience, reflection, reasoning, or communication, as a guide to belief and
action"[4][page needed]
 "purposeful, self-regulatory judgment which results in interpretation, analysis, evaluation,
and inference, as well as explanation of the evidential, conceptual, methodological,
criteriological, or contextual considerations upon which that judgment is based"[5]

 "includes a commitment to using reason in the formulation of our beliefs"[6]

~ Malcolm S. Forbes
 History and etymology
 The critical thinking philosophical frame
traces its roots in analytic philosophy and
pragmatist constructivism which dates
back over 2,500 years.
 Meaning
 Critical thinking clarifies goals, examines
assumptions, discerns hidden values,
evaluates evidence, accomplishes actions,
and assesses conclusions.

ready to defend their most precious possession – their ignorance.”
~ Hendrik Van Loon
 In sum:
 "A persistent effort to examine any
belief or supposed form of knowledge in
the light of the evidence that supports it
and the further conclusions to which it
tends.”( b Edward M. Glaser (1941). An
Experiment in the Development of Critical
Thinking. New York, Bureau of
Publications, Teachers College, Columbia
University. ISBN 0-404-55843-7.)

12. Habits or traits of mind
 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.[16] When individuals
possess intellectual skills alone,
without the intellectual traits of
mind, weak sense critical thinking
results. Fair-minded or strong sense
critical thinking requires intellectual
humility, empathy, integrity,
perseverance, courage, autonomy,
confidence in reason, and other
intellectual traits. Thus, critical
thinking without essential
intellectual traits often results in
clever, but manipulative and often
unethical or subjective thought.

14. Example thinker
 raises important 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 practical consequences
 communicates effectively with others in figuring out solutions to
complex problems, without being unduly influenced by others'
thinking on the topic.

15. Critical Thinking as Defined by the National Council for
Excellence in Critical Thinking, 1987
 A statement by Michael Scriven & Richard Paul, presented at the 8th Annual
International Conference on Critical Thinking and Education Reform, Summer
1987.
 Critical thinking is the intellectually disciplined process of actively and skillfully
conceptualizing, applying, analyzing, synthesizing, and/or evaluating information
gathered from, or generated by, observation, experience, reflection, reasoning,
or communication, as a guide to belief and action. In its exemplary form, it is
based on universal intellectual values that transcend subject matter divisions:
clarity, accuracy, precision, consistency, relevance, sound evidence, good reasons,
depth, breadth, and fairness. It entails the examination of those structures or
elements of thought implicit in all reasoning: purpose, problem, or question-at-
issue; assumptions; concepts; empirical grounding; reasoning leading to
conclusions; implications and consequences; objections from alternative
viewpoints; and frame of reference. Critical thinking — in being responsive to
variable subject matter, issues, and purposes — is incorporated in a family of
interwoven modes of thinking, among them: scientific thinking, mathematical
thinking, historical thinking, anthropological thinking, economic thinking, moral
thinking, and philosophical thinking.
