Asimov employed the wide-angle lens for his view of life and it is a pity that his largest milestone, the Foundation trilogy, was written before sf authors were able to think of their books as books, rather than as short stories or serials in ephemeral magazines (or magazines that would have been ephemeral but for the dedication of fans). Conceived as one organic whole, the Foundation series would have undoubtedly risen to greater majesty….

Asimov has developed into one of the polymaths of our day, producing a stream of popularisations of various scientific disciplines. The popularity of his novels continues. Like many another writer, Asimov began in subversive vein, prophesying change and barbarism; but, a generation later, such ideas lose their sting and become safe for a general public. Increasingly, one sees the solid conservative faith in technology in Asimov's novels. His short stories often err on the side of facetiousness. (p. 269)
