  1. What is Critical Thinking, Anyway?

  2. What does it mean “to think?” To have a conscious mind, reasoning, remembering experiences, making rational decisions, etc. To employ one's mind rationally and objectively in evaluating or dealing with a given situation.

  3. The Nature of the Experience of Thinking…. Where do thoughts come from? If you were a “brain in a vat,” would you have thoughts? What is the product of thinking? Is “feeling” different from thinking? What are thoughts “made of”?

  5. Critiquing Thinking Are some thoughts and ideas better or worse than others? How do we determine what to believe and the degree to which we should believe? Foundation for Critical Thinking says we should weigh claims against Universal Intellectual Values Clarity Accuracy Precision Consistency Relevance Good Evidence Good Reasons Depth Breadth

  6. Rational, Logical Thinking To think rationally is to make inferences from beliefs that are justified by the laws of logic. Only one of these is a rational thought. If it is sunny and warm, Tim and Tina are at the beach. It is sunny and warm, so Tim and Tina are at the beach. If it is sunny and warm, Tim and Tina are at the beach. Tim and Tina are at the beach, so it is sunny and warm. The laws of logic tell us what inferences we can make.

  7. Critical Thinking Examines the structures or elements of thought implicit in all reasoning. Inference: if A is true, then B is true. Inference: if B is false, then A is false. and why are you thinking it…..
