The document summarizes the argument from analogy, which aims to show that we are justified in inferring the existence of other minds based on analogies to our own behavior and thoughts. It notes that Norman Malcolm argued the argument from analogy does poorly in this aim. The document will assess Malcolm's objection to the argument from analogy as well as responses from Wittgenstein, Price, and Hampshire in defense of the argument from analogy. It also discusses Russell's view that believing in other minds requires postulating that thoughts or feelings cause bodily acts, even when observation does not enable knowing if the thoughts are present.
