Inductive reasoning and Cross-induction

This post is an introduction to the method of inductive reasoning and the problem of induction. It also introduces an interesting answer to the problem, called cross-induction (this post is more or less a transcription of a video that I made a couple of months ago, feel free to check it out:)


Why do you think there's going to be a tomorrow? The future is uncertain. You don’t know what it brings. But still you make claims about it. Claims like:

  1. The sun will rise tomorrow.

We don’t know that. But still, we all believe that. Why? What’s our rational justification for believing anything about the future?

Russell's Teapot

This post provides a short explanation of Russell's teapot and is basically a transcription of a video that I made a couple of months ago (feel free to check it out):


Imagine I make the following claim:

  1.  There is a teapot - which is too small to be seen by telescopes - and it orbits the sun somewhere around mars.


Let's say I don't offer any proof or evidence for my claim. Would you take my claim to be true?

This analogy was put forth by Bertrand Russell (1872-1970), who wanted to demonstrate that even though no one can disprove the existence of such a teapot (since we said that it's too small to be observed anyways), he would expect no one to believe in its existence either.
