Tools of Thinking: Understanding the World Through Experience and Reason
by James Hall
The professor has a combined background in science and philosophy. At the start, the profess identifies four crucial tools in thinking: intuition, memory, reason, and association. This collection was mentioned several times. However, the course really focuses on the relationship between experience and reason in understanding the world.
The course started by discussing the epistemologies of Plato and Aristotle. Plato thinks all knowledge is from “intuition” that is given to people without their effort. People just need to escape from the “shackle in the cave” and reestablish their connection with the Ideal. Aristotle, on the other hand, thinks knowledge is from observation and experience. People form ideas by organizing their experiences to establish a world-view. Both of them value the reasoning process and a critical step in gaining knowledge.
The course then contrasts rationalism and empiricism. Both regard, respectively, reason and experience as the primary source of knowledge while holding an intense skepticism against the other. The discussion leads to modern empiricism, which is today’s methodology in science. Under this doctrine, experience and reason interact and advance in tandem. Reason is based on experience, and it, in turn, provides a framework for experience interpretation. People form hypotheses, which can be inductions from limited experience or cooked-up theories to explain the experiences. Hypotheses are verified (or falsified) by more experiences, often in the form of designed and controlled experiments. Both experiences and reasoning are fallible; we expect future work will make our understanding closer to reality. We also have some guiding principles to filter the hypotheses that we will take seriously. One is Popper’s theory of falsification, which says any scientific theory must identify a set of possible experiences that can falsify it. Namely, they can be put to the test by experience. The other principle is Occam’s razor, which says one should use a minimal set of hypotheses to explain given experiences. Given the same explanation power, one should choose the hypotheses that are the simplest and least controversial.
Another part of the course is on formal logic. The teacher started with the logic system of Aristotle and Euclid. He then moved to the modern logic theories based on truth tables and Boolean algebra. The modern logic system can capture and process more complex logical relationships. One key in logic discourse is distinguishing the set (“all” and “some”), for which the Van Diagram is a valuable tool. The professor also briefly discussed several common logic fallacies, although they are not discussed in the context of logic theories.
Overall, the course provides interesting perspectives. However, it does not teach anything more than standard scientific methods at the college level. The title of the course is too broad. For example, the book does not cover all “thinking” activities, only those related to scientific works.
