Without question this goes at the very top of my “books I wish I had read 15 years ago” list. Way too much packed in here to do it justice. Perhaps later I’ll write a proper review. Some quick notes:
You will realize how stupid you are, and how your ideas and beliefs are not your own, that is you haven’t spent the countless hours it takes to really work things out for yourself, you have merely adopted positions that fit your identity.
Almost every topic is infinitely more complicated and nuanced than at first sight.
Almost nobody thinks anymore. Even people who write books these days are mostly writing derivative crap.
If we want to be thinkers, and have sharp intellects, and not merely recite what others have said, then we must devote time exclusively to thinking problems through from first principles.
Hazlitt recommends a 1:1 ratio of time spent thinking to reading.
Before reading a book on a topic, you should spend some time thinking on that topic and see what you already know, what you think you know, and most importantly what problems or contradictions you see that you would like to resolve.
Hazlitt, like Deutsch, sees all thinking as problem solving. Without problems, humans would have no need for thought.
You should keep a running list of what you consider the most important problems you want to solve, and constantly be moving closer to solutions. These could be existential, philosophical, political, economic, ethical, or anything. (They could also be mathematical or scientific of course but this book isn’t about those kinds of problems).
Some problems can be worked out in a half hour. Others will take years. Carry them with you. You do not need to have a strong opinion on everything. If asked about a certain political issue, responding with “I haven’t thought that issue through far enough to have a strong opinion on it” is ok.
That being said, once you think you have decided something, have the courage to declare it and defend it. Don’t waiver or caveat everything. If you’ve done some serious thinking, reading, and writing on an issue, then don’t use language like “It’s my belief that X” or “I could be wrong but isn’t X?” Or “Perhaps X”. Just come right out with what you believe.
While thinking on a topic you should concentrate all your focus on it. Sometimes creative and useful lines of reasoning do pop into consciousness when we are relaxing, like when in the shower, but usually these come after hours of effort full concentration on a subject.
There are several different techniques for approaching problems that are useful when you’re stuck on a problem. They are all discussed in the book.
As you read, you should read slowly and think over what you are reading. If you think you can anticipate the author’s argument, then stop reading and try to make the argument yourself. If you think the author is wrong, stop reading and talk out why you think the authors wrong. You should be able to write out a persuasive explanation. If you can’t, then chances are you don’t actually know that the author is wrong, you just wish it to be so.
If you read something intelligent or persuasive you are likely to forget it in time. If you turn the ideas around in your own mind and come up with your own firm solutions, you will never forget it.
Because there are about a hundred million books, and a human can only read 1 or 2 thousand at most, books should be chosen very carefully.
Solving problems that have been solved already long ago is not a waste of time, because you get practice in creativity. Creative solutions to problems is the name of the game. Nothing else matters.
If you are a careful thinker, you will have thought through all objections to your views far in advance, and you aren’t liable to be caught off guard in a debate or conversation. In fact, your views are nothing more than the collection of ideas that you haven’t been able to contradict yet.
But still, conversations with smart people will help you grow as a thinker and strengthen your arguments. If you are wrong about something, have the humility to admit it.
So much more. This book is a gem. For better or worse it has changed everything.
