Phrenology is a system of Mental Philosophy. It enquires into the quality and condition of the mind, estimating the faculties, sentiments, and propensities of the individual, without being deceived by personal esteem or the voice of partial praise; for as it too frequently occurs that minds of the highest order are more or less under the influence of self love, or a desire for the admiration of others, so are they blinded to their own weaknesses and in some measure rendered incapable of acknowledging their faults even to themselves.
