Proper Names and Description——Russell's Criticism to Frege

Proper name and reference are two basic concerns in the philosophy of language. According to Frege, proper names are wide in range and refer to the reality through sense. Differently, Russell distinguishes between proper name and description. The former refers to the reality directly while the latter, which can only be meaningful within context, does not designate a single object directly. He also points out the differences between proper name and ordinary name.
