# On Induction explained — The Problems of Philosophy

> Chapter companion for The Problems of Philosophy by Bertrand Russell.

## What happens

Russell examines the principle of induction, questioning whether past uniformities provide any rational ground for expecting future occurrences. He distinguishes between the instinctive formation of expectations based on habit and the logical justification for such expectations, concluding that induction can only yield probability, not certainty.

## Themes in this chapter

### Knowledge and Certainty

Russell questions whether inductive inferences can yield certain knowledge, arguing that they only provide probability.

### Truth and Falsehood

The chapter explores the truth status of beliefs about the future and unobserved past, based on the principle of induction.

## Key lines

> The question we have now to consider is whether such an extension is possible, and if so, how it is effected.

We must now ask whether we can legitimately extend our knowledge beyond our immediate experience, and if so, by what method.

_Sets up the central problem of the chapter: the justification of inductive inference._

> The mere fact that something has happened a certain number of times causes animals and men to expect that it will happen again.

Simply because an event has occurred repeatedly in the past, both humans and animals naturally come to anticipate its recurrence.

_Highlights the psychological basis of induction, as opposed to its logical justification._

> Thus probability is all we ought to seek.

Therefore, we should only aim for probabilistic conclusions, not absolute certainty.

_Russell's conclusion that induction can only provide probable knowledge._
