Of the other comparisons that are usually made, we may observe in general, that, as they consist in comparing the iniquitous practice of slavery with other iniquitous practices in force among other nations, they can neither raise it to the appearance of virtue, nor extenuate its guilt. The things compared are in these instances both of them evils alike. They call equally for redress[098], and are equally disgraceful to the governments which suffer them, if not encourage them, to exist. To attempt therefore to justify one species of iniquity by comparing it with another, is no justification at all; and is so far from answering the purpose, for which the comparison is intended, as to give us reason to suspect, that the _comparer_ has but little notion either of equity or honour. We come now to those scenes of felicity, which slaves are said to enjoy. The first advantage which they are said to experience, is that of _manumission_. But here the advocates for slavery conceal an important circumstance. They expatiate indeed on the charms of freedom, and contend that it must be a blessing in the eyes of those, upon whom it is conferred. We perfectly agree with them in this particular. But they do not tell us that these advantages are _confined_; that they are confined to some _favourite domestick_; that not _one in an hundred_ enjoy them; and that they are _never_ extended to those, who are employed in the _cultivation of the field_, as long as they can work. These are they, who are most to be pitied, who are destined to _perpetual_ drudgery; and of whom _no one whatever_ has a chance of being freed from his situation, till death either releases him at once, or age renders him incapable of continuing his former labour. And here let it be remarked, _to the disgrace of the receivers_, that he is then made free, not--_as a reward for his past services_, but, as his labour is then of little or no value,--_to save the tax_[099].
