I’m utterly delighted to have just found on line a pdf version of Henry Martyn’s 1701 pamphlet Considerations on the East-India Trade. This work was first brought to my attention by Doug Irwin’s indispensable book Against the Tide (1996). Doug quotes much from Martyn and even suggests that Martyn’s “analytical contribution to the case for free trade” might surpass even that of Adam Smith.
It’s only now, though, that I found Martyn’s pamphlet. I will read it ASAP.
Here’s one of my favorites of the Martyn quotations appearing in Doug’s book:
If the same Work is done by one, which was done before by three; if the other two are forc’d to sit still, the Kingdom got nothing before by the Labour of the two, and therefore loses nothing by their sitting still.
(This quotation is found on page 57 of Doug’s book, but it is quoted here as it appears in the on-line version of Martyn’s pamphlet.)
