Rated 5 out of 5 by from Entertaining and Philosophical Professor Patrick Grim presents interactive examples in “The Philosopher’s Toolkit” that you won’t see anywhere else, which will indeed help you to become “The Most Rational Person in Any Room.” His lectures are engaging and entertaining. He starts by giving the background & context for each technique, taken from the history of Philosophy and Science; then he cleverly applies the techniques to current issues that cry out for our critical thinking. He covers areas such as the bogus arguments we see online, “fake news” and political rhetoric, and revealing the sneaky psychological techniques used in advertising. I loved the lectures on Game Theory and use of Models. Prof. Grim lists the benefits of thinking with models, including “to show the simple core of complex processes and the complexities behind simple ones.” He concludes that their most important use is “to suggest new questions.” This course is the answer to the question “Do you want to become the Most Rational Person in Any Room?” Yes, please!

Rated 5 out of 5 by from Great lessons and examples Having taken an intro to philosophy in college, I was skeptical that this would be valuable and concrete enough. Much to my appreciation, it has great lessons, hands on examples and enough repetition for some (most?) of it to stick in my mind. I would highly recommend this for anyone who wants to be able to pause and think vs. being reactive and emotional.

Rated 4 out of 5 by from Great course with a silly mistake It's a great course and I am enjoying it but in the third video (around minute 2) there is a quite silly mistake. In the example, it is said/written that the length is 8 inches squared but the length is measured only in inches. Inches squared is used to measure an area, eventually.

Rated 5 out of 5 by from Excellent exposure to concepts of rationality I think this is an excellent introduction to tools of rationality with great explanations & great visuals . I would have been happier if the concepts would have been explained in greater depths to solve more complicated problems even if it meant sacrificing the number of concepts explained

Thinking is at the heart of our everyday lives, yet our thinking can go wrong in any number of ways. Bad arguments, fallacious reasoning, misleading language, and built-in cognitive biases are all traps that keep us from rational decision making. What can we do to avoid these traps and think better? Is it possible to think faster, more efficiently, and more systematically? The Philosopher's Toolkit: How to Be the Most Rational Person in Any Room, taught by award-winning Professor Patrick Grim of the State University of New York at Stony Brook, arms you against the perils of bad thinking and supplies you with an arsenal of strategies to help you be more creative, logical, inventive, realistic, and rational in all aspects of your daily life.


Patrick Grim

In the end, imagining a world of fact without value is quite nearly impossible for creatures like us. Our lives are woven in terms of the things we value.

How We Think and How to Think Better

01: How We Think and How to Think Better

Thinking is fundamental to our daily lives, and this introduction surveys the philosopher's toolkit, strategies to improve our thinking-visualization, simplification, the principles of debate, and techniques for social reasoning. Because the best philosophy is done in conjunction with other disciplines, you'll apply these tools to economics, psychology, and more.

33 min
Cool Rationality and Hot Thought

02: Cool Rationality and Hot Thought

Which is a better tool for decision making, reason or emotion? As this lecture argues, both cool rationality and hot emotion have their place. Understanding the strengths and weaknesses of each can help us make better decisions, both in the heat of a moment and during long-term analysis.

30 min
The Strategy of Visualization

03: The Strategy of Visualization

Pull out your pen and paper and put "conceptual visualization" to work. Humans excel at pattern recognition, and what we see in our mind's eye can aid us in solving even the most daunting of puzzles, from the Pythagorean theorem to Special Relativity. You'll see how sketches and matrices are powerful aids for information management.

30 min
Visualizing Concepts and Propositions

04: Visualizing Concepts and Propositions

Explore the most basic elements of thought to prepare for the coming lectures. Concepts are the atoms of thought, expressed by words and illustrated by Venn diagrams and concept trees. Words form sentences-or propositions-which are the molecules of thought. Together, concepts and propositions provide a structural framework to express thought and convey information.

30 min
The Power of Thought Experiments

05: The Power of Thought Experiments

Harness the power of your imagination with this hands-on lecture, which introduces several strategies for solving real-world problems with thought experiments. As lessons from economics, business, ethics, and physics show, the imagination is one of our finest tools for exploring reality.

29 min
Thinking like Aristotle

06: Thinking like Aristotle

So far, the course has emphasized visual techniques for logical thinking. In this lecture you'll discover one of the greatest developments of human thought. Aristotle's "square of oppositions" is the core of our logical system and provides a bridge to connect visualization with the flow of rational argument.

30 min
Ironclad, Airtight Validity

07: Ironclad, Airtight Validity

What makes an argument valid? Continue your study of Aristotelian logic by looking at how propositions form airtight arguments. By mapping out the logic of syllogisms with Venn diagrams, you'll enhance your deductive reasoning skills-and you'll see that the unfortunate trade-off for an absolutely airtight syllogism is that it doesn't really offer any new information.

31 min
Thinking outside the Box

08: Thinking outside the Box

Creativity can't be taught, but it can be cultivated. Take a break from the traditional lecture with this enjoyable workshop on creative, sideways thinking. Here you'll participate in a number of engaging exercises designed to break your standard habits of thought and help you solve problems by thinking outside the box.

29 min
The Flow of Argument

09: The Flow of Argument

Ironclad, deductive syllogisms won't get us very far in terms of new information, so this lecture looks beyond that simple framework and introduces you to the flow of complex arguments. By understanding logical "flow," you'll have the tools to determine an argument's strengths and weaknesses. Is the conclusion inescapable, or merely probable? How "sound" is the argument?

30 min
Simple Heuristics That Make Us Smart

10: Simple Heuristics That Make Us Smart

Dive into the world of heuristics, simple rules of thumb that guide us through immediate decisions when we lack the time needed for logical analysis. You'll reflect on the wisdom of crowds, find out why German college students do better than Americans on U.S. demographic quizzes, and consider the utility of "good enough" solutions.

31 min
Why We Make Misteaks

11: Why We Make Misteaks

The bad news is that to err is human. Thanks to information biases, selective memories, and unreliable heuristics, systematic error is built into the way we think. The good news is that once we become aware of these biases, we can compensate for them. This lecture shows you how.

29 min
Rational Discussion in a Polarized Context

12: Rational Discussion in a Polarized Context

How do you have a rational discussion with someone with a radically different viewpoint? Political polarization is real, and media gives us instant access to slanted sources. Here you'll unpack several negotiation strategies to reconcile two sides in an argument-and examine the signs of a hopelessly irrational discussion.

30 min
Rhetoric versus Rationality

13: Rhetoric versus Rationality

Guard yourself against the perils of rhetoric. By learning the ins and outs of ethos, pathos, and logos, you'll be prepared to parry manipulative rhetoric as it comes-especially from the broadcast media. You'll also develop your ability to visualize patterns of exchange, which can assist you with making persuasive presentations.

30 min
Bogus Arguments and How to Defuse Them

14: Bogus Arguments and How to Defuse Them

Tour the world of bad arguments. From ad hominem attacks to false alternatives and hasty generalizations, this lecture presents the most common logical fallacies and offers you the chance to test your knowledge against a myriad of examples. But be forewarned: There's no guarantee that a bad argument is committing just one fallacy.

28 min
The Great Debate

15: The Great Debate

Continue to hone your argumentative skills by evaluating a debate over the future of freedom and democracy. You'll analyze the rhetoric and see the strategies at work in a real back-and-forth, and you'll come away with a sharpened ear for appeals to emotion, syllogisms, and other rhetorical techniques of persuasion.

29 min
Outwitting the Advertiser

16: Outwitting the Advertiser

Recommended by doctors! Low fat! Call today! The world of advertising is filled with psychological manipulation, misleading half-truths, and magic words designed to get us to buy. This lecture cuts through the spin to show us the advertiser's favorite techniques, from beautiful spokespeople to empty messaging.

30 min
Putting a Spin on Statistics

17: Putting a Spin on Statistics

Facts and stats are clear and objective, right? Of course not. Statistics are great because they give us information in an easy-to-understand way, but they can also be dangerously misleading. Something as simple as the choice between mean, median, and mode can skew the facts. The ability to evaluate statistics allows you to draw your own conclusions.

32 min
Poker, Probability, and Everyday Life

18: Poker, Probability, and Everyday Life

Life is filled with chance, and unfortunately it's not as easy to navigate as counting face cards. This survey of probability will allow you to deal with chance more rationally. You'll study the law of large numbers, how to calculate the probability of one or more events, and the gambler's fallacy that keeps casinos in business.

29 min
Decisions, Decisions

19: Decisions, Decisions

Turn your attention to decision theory, the surefire way to make the most rational decision with the evidence you have. The key is to maximize expected utility. Doing so can tell you everything from which wine to buy for a dinner party to how to respond to an influenza outbreak. Pascal even used decision theory to determine his belief in God.

30 min
Thinking Scientifically

20: Thinking Scientifically

What's the difference between real science and pseudoscience? What's wrong with astrology and phrenology? Find out how to build your own pseudoscience, complete with ambiguous phenomena and post-hoc modifications, so you'll know what to watch out for when you're presented with something that looks like science but doesn't pass the test of a rigorous scientific theory.

30 min
Put It to the Test—Beautiful Experiments

21: Put It to the Test—Beautiful Experiments

Analyzing the structure of scientific experiments is an important part of the philosopher's toolkit. The risks, power, and limits of experimentation can help you back your own claims and evaluate the claims of others. Here you'll examine the parts of a good experiment-control groups, randomized testing, and what to do with unexpected results

31 min
Game Theory and Beyond

22: Game Theory and Beyond

Where decision theory leaves off, game theory begins. This lecture walks you through the techniques of decision making in a social context. You'll look at the cooperation and competition inherent to the Prisoner's Dilemma, and you'll reflect on behavioral economics, a field that studies irrational action.

30 min
Thinking with Models

23: Thinking with Models

Synthesize the earlier lectures on visualization, simplification, and thought experiments and check out the benefits of thinking with models. The three-stage model-input, mechanism, and output-is a great way to put your toolkit strategies to work, whether you want to predict tomorrow's weather, explain why the moon exists, or understand segregated neighborhoods.

30 min
Lessons from the Great Thinkers

24: Lessons from the Great Thinkers

Conclude the course with a journey through the minds of great thinkers from Plato and Aristotle to Darwin and Einstein. You'll consider what made them great thinkers, and you'll pick up a few tips to improve your own thinking.
