I am not intent on setting Cobbett forth as a model of wisdom. I simply maintain that his common-sense was adequate to the judgment of vaccination, and that it was correctly exercised. Of physiology and hygiene he was as ignorant as his contemporaries; but if a lotion were sold to prevent toothache, and it did not prevent toothache, it would be safe to denounce its vendors as quacks, even though the vendors happened to be the Royal College of Physicians and the Royal College of Surgeons. The causes of disease were unconsidered in Cobbett’s days. It was not asked why people suffered from smallpox and other fevers, nor whether fevers were avoidable. Such maladies were accepted like bad weather, and encountered by medical dodges, or by charms like vaccination, the more irrational and nasty being taken for the more effective. Cobbett himself, if he did not believe in vaccination, believed in inoculation with smallpox. He had his children poxed in infancy, and when he argued against vaccination, it was in the confident possession of a surer prophylactic. Taking smallpox for a probable calamity that could only occur once in a lifetime, it seemed to him expedient to incur the disease when convenient, and to have done with the dread of it. How far he was mistaken in this course I need not stay to debate. Suffice it to say, that he thought he could make sure that smallpox was smallpox, whilst what cowpox might be none could tell, especially after transmission through arms and constitution unnumbered and unknown.
