Pride differs in many things from vanity, and by gradations that never blend, although they may be somewhat indistinguishable. Pride may perhaps be termed a too high opinion of ourselves founded on the overrating of certain qualities that we do actually possess; whereas vanity is more easily satisfied, and can extract a feeling of self-complacency from qualifications that are imaginary.
