It needs little to prove error can never be advantageous for mankind; it is ever founded upon his ignorance, which is itself an acknowledged evil; it springs out of the blindness of his mind to acknowledged truths, and his want of experience, which it must be admitted are prejudicial to his interests: the more importance, therefore, he shall attach to these errors, the more fatal will be the consequences resulting from their adoption. Bacon, the illustrious sophist, who first brought philosophy out of the schools, had great reason when he said, "The worst of all things is deified error." Indeed, the mischiefs springing from superstition or religious errors, have been, and always will be, the most terrible in their consequences--the most extensive in their devastation. The more these errors are respected, the more play they give to the passions; the more value is attached to them, the more the mind is disturbed; the more they are insisted upon, the more irrational they render those, who are seized with the rage for proselytism; the more they are cherished, the greater influence they have on the whole conduct of our lives. Indeed, there can he but little likelihood that he who renounces his reason, in the thing which he considers as most essential to his happiness, will listen to it on any other occasion.
The slightest reflection will afford ample proof to this sad truth: in those fatal notions which man has cherished on this subject, are to be traced the true sources of all those prejudices, the fountain of all those sorrows, to which he is the victim. Nevertheless, as we have elsewhere said, utility ought to be the only standard, the uniform scale, by which to form a judgment on either the opinions, the institutions, the systems, or the actions of intelligent beings; it is according to the measure of happiness which these things procure for us, that we ought either to cover them with our esteem, or expose them to our contempt. Whenever they are useless it is our duty to despise them; as soon as they become pernicious, it is imperative to reject them; reason imperiously prescribes that our detestation should be commensurate with the evils which they cause.
