 A well-known objection to this account is that similarity has the wrong logical properties. Goodman (1976: 4–5) points out that similarity is symmetric and reflexive yet representation isn’t. If object \(A\) is similar to object \(B\), then \(B\) is similar to \(A\). But if \(A\) represents \(B\), then \(B\) need not (and in fact in most cases does not) represent \(A\). Everything is similar to itself, but most things do not represent themselves. So this account does not meet our fourth condition of adequacy for an account of scientific representation insofar as it does not provide a direction to representation.
