In a vigorously argued paper, Mr J. P. Cooper has attacked my interpretation of Henry VII's reign. If the point at issue were only Mr Cooper's view of my methods and scholarship – or, for that matter, my view of his – I should feel neither justified nor inclined to trouble anyone again with these problems. But Mr Cooper is almost as much concerned to prove Henry VII rapacious as he is sure that I am wrong; and the truth about Henry VII's government deserves all the elucidation it may need. If, therefore, I reluctantly recur to an argument in which I have already had an extended say, it is because I believe Mr Cooper to be in error on a matter of first-rate importance; I hope to show that he has arrived at a mistaken view from partial, and partially misinterpreted, evidence. In a field in which things are far from clear or straightforward this is neither surprising nor shocking; it is more disconcerting to find that one who so readily chastises others for their supposed failings should himself be strangely inclined to inaccuracy in discussing other people's views and even in transcribing documents. A self-appointed hound of heaven ought to be more precise in his quest.

I must once again state the purpose of my earlier article.
