“The Rationalist Delusion” Limitations of reason in searching for truth

Knowledge Questions: What is the relationship between reason and intuition? Do we use reason or intuition more when determining truth?

The following are passages from Jonathan Haidt’s book, The Righteous Mind: Why Good People Are Divided by Politics and Religion

Anyone who values truth should stop worshipping reason. We all need to take a cold hard look at the evidence and see reasoning for what it is. The French cognitive scientists Hugo Mercier and Dan Sperber recently reviewed the vast research literature on motivated reasoning (in social psychology) and on the biases and errors of reasoning (in cognitive psychology). They concluded that most of the bizarre and depressing research findings make perfect sense once you see reasoning as having evolved not to help us find truth but to help us engage in arguments, persuasion, and manipulation in the context of discussions with other people…

In the same way, each individual reasoner is really good at one thing: finding evidence to support the position he or she already holds, usually for intuitive reasons. We should not expect individuals to produce good, open-minded, truth-seeking reasoning, particularly when self-interest or reputational concerns are in play.

Truthiness and Fake News

How do we determine what is true? What role do emotions play in our acquisition of knowledge?

In this clip from 2005, Stephen Colbert coins his phrase, “truthiness” which to some degree portended the coming of “fake news” and its pervasiveness a decade later.

Facts are believable and “true if they “feel” true. This also lends itself to a discussion of the role of emotion in the acquisition of knowledge.

Neil deGrasse Tyson on the “three kinds of truth”

In this 5 minute clip, from the Joe Rogan podcast, Neil deGrasse Tyson discusses his idea of the three different kinds of “truth.” It’s an interesting discussion on the definition of the word but also the implications of how we use words. Short enough to be interesting but not so long as to be tedious. For a tedious conversation on truth, see the previous post on the conversation between Sam Harris and Jordan Peterson.

I linked the video at the start of the relevant conversation.

Below is just the audioclip that you can stream just the audio if youtube is blocked and download below that if you just want the mp3 file.

SPEAKING OF “TRUTH” WITH JORDAN B. PETERSON

We spent two hours debating what it means to say that a proposition is (or seems to be) “true.” This is a not trivial problem in philosophy. But the place at which Peterson and I got stuck was a strange one. He seemed to be claiming that any belief system compatible with our survival must be true, and any that gets us killed must be false.
