Empathising with other minds

If to know a mind requires that you are that mind, how can you know for certain whether other minds exist? This is a problem in philosophy known as the problem of other minds, and philosophers have rendered this problem insoluble.

But in science, and in everyday life, we don’t usually require absolute certainty, and are happy to rely on provisional truth. We formulate hypotheses, test them, and as long as we cannot falsify these hypotheses, we accept them to be true. In testing whether something has subjectivity or not, we use a systematic common sense approach which comes rather naturally to us. The technical term for this approach is called empathy.
