He has been called the earliest professional author in our language, and if that is not strictly true, he is at any rate the earliest literary journalist.

His output of work was enormous; he wrote on any and every subject; there was no event whether in politics or letters or discovery but he was not ready with something pat on it before the public interest faded.

It followed that at a time when imprisonment, mutilation, and the pillory took the place of our modern libel actions he had an adventurous career.

In politics he followed the Whig cause and served the Government with his pen, notably by his writings in support of the union with Scotland, in which he won over the Scots by his description of the commercial advantage which would follow the abolition of the border.
This line of argument, taken at a time when the governing of political tendencies by commercial interests was by no means the accepted commonplace it is now, proves him a man of an active and original mind.
His originality, indeed, sometimes over-reached the comprehension both of the public and his superiors; he was imprisoned for an attack on the Hanoverian succession, which was intended ironically; apparently he was ignorant of what every journalist ought to know that irony is at once the most dangerous and the most ineffectual weapon in the whole armoury of the press.

The fertility and ingenuity of his intellect may be best gauged by the number of modern enterprises and contrivances that are foreshadowed in his work.
