It is not only the general principles of justice that are infringed, or at least set aside, by the exclusion of women, merely as women, from any share in the representation; that exclusion is also repugnant to the particular principles of the British Constitution. It violates one of the oldest of our constitutional maxims...that taxation and representation should be co-extensive. Do not women pay taxes?
