What is Critical Thinking?

• Critical thinking df. The careful, deliberate
  determination of whether we should accept,
  reject, or suspend judgment about a claim and
  of the degree of confidence with which we should
  accept or reject it.

Alternative Thinking Styles

• One approach to thinking is similar to the way in
  which a sponge reacts to water by absorbing.
• Advantages
• The more information you absorb about the world,
  the more capable you are of understanding its
  complexities. For example, it would be difficult
  to judge a sociological theory before you had
  absorbed a core of knowledge about sociology.

Alternative Thinking Styles II

• A second advantage of the sponge approach is that
  it is relatively passive. The primary mental
  effort involves concentration and memory.
• Disadvantages
• The sponge approach provides no method for
  deciding which information to believe and which
  to reject.

Alternative Thinking Styles III

• The sponge approach emphasizes knowledge
  acquisition.
• Critical thinking stresses active interaction
  with knowledge as it is being acquired.
• An individual that takes the sponge approach to
  learning may underline or highlight key words and
  sentences. Her mission is to find and understand
  what the author has to say. She memorizes the
  reasoning, but does not evaluate it.

A Critical Thinking Approach

• A critical thinking approach requires that the
  reader ask herself a number of questions to
  clarify logical steps in the material and to help
  identify important omissions.

GOALS OF CRITICAL THINKING

• What is critiqued is the ideas of people, not the
  people themselves who hold the ideas.
• The goal of philosophy is knowledge through a
  disinterested search for truth, not winning or
  simply appearing to defeat another in argument.
• Critical thinking helps both ourselves and others
  when it helps us recognize that a position,
  theory, or idea is incomplete or unclear,
  insufficiently supported, or in some other way
  unconvincing, and thus helps us to arrive at the
  truth which is the goal of knowledge seekers.

Thinking and Feeling

• When you first encounter a conclusion, you do so
  with a history. You have learned to care about
  certain things, to support particular interests,
  and to disregard some particular claims. You
  will be thinking critically in the midst of
  existing opinions. You have emotional
  commitments to these opinions. Sometimes it is
  good to put your feelings aside for a while.
  This will enable you to listen to others
  arguments openly. The danger of being
  emotionally involved in an issue is that you may
  fail to consider potential good reasons for other
  positions.
• One doesn't discover new lands without consenting
  to lose sight of the shore for a very long time.
  --Andre Gide

Thinking and Feeling

• M.Neil Browne and Stuart Keeley
• As part of the human tendency to dichotomize or
  think in extremes, those who emphasize critical
  thinking as an educational necessity sometimes
  express contempt for emotions. All off us know
  that unrestrained feelings can get us into
  trouble. They seem to encourage us to act first
  and think later. But any tool can be misused.
  Emotions are an invaluable aspect of each of us.
  Many of the feelings that we have are the result
  of deep thought. We get angry at certain
  behavior for very good reasons. We may admire
  specific people for some powerful reasons. So
  how should you feel about your feelings as you
  try to think critically? Our advice is to
  recognize your feelings to the extent possible,
  respect those that are the result of careful
  reflection and try, as best you can, to prevent
  others from cluttering your reasoning.
