In a word, those who have most vigorously taken up the cause of the theological systems, have been taxed with atheism and irreligion; the most zealous partizans have been looked upon as deserters, have been contemplated as traitors; the most orthodox theologians have not been able to guarantee themselves from this reproach; they have mutually bespatered each other; prodigally lavished, with malignant reciprocity, the most abusive terms: nearly all have, without doubt, merited these invectives, if in the term atheist be included those men who have not any idea of their various systems, that does not destroy itself, whenever they are willing to submit it to the touchstone of reason. From whence we may conclude, without subjecting ourselves to the reproach of being hasty, that error will not stand the test of investigation; that it will not pass the ordeal of comparison; that it is in its hues a perfect chamelion; that consequently it can never do more than lead to the most absurd deductions: that the most ingenious systems, when they have their foundations in hallucination, crumble like dust under the rude band of the assayer; that the most sublimated doctrines, when they lack the substantive quality of rectitude, evaporate under the scrutiny of the sturdy examiner, who tries them in the crucible; that it is not by levelling abusive language against those who investigate sophisticated theories, they will either be purged of their absurdities, acquire solidity, or find an establishment to give them perpetuity; that moral obliquities, can never be made rectilinear by the mere application of unintelligible terms, or by the inconsiderate jumble of discrepant properties, however gaudy the assemblage: in short, that the only criterion of truth is, _that it is ever consistent with itself_.
