Why do we use a different key to sign than to encrypt

Not GPG specific, but I was wondering if someone could point me in the
direction of some resources that explain why we use different keys to
sign and encrypt (for cases where the same key _could_ do both e.g.
RSA).  I cant seem to pick anything up on google.
