‘The critic who refuses to contradict himself is no critic at all. He is a grub: a pure grub.’ (Johannes Speyer)
N.B. I may be wrong, but I think Speyer had a certain person – or group of people – in mind when he said this, which goes some way to explain why he uses the masculine pronoun only. I say this, of course, to put off those who might imagine that Speyer was not open to the idea of female critics. He most certainly was.
I might add, also, that the phrase ‘pure grub’ was a favourite of Speyer’s – never written, but very often said. Meanwhile, Leo Barnard (quoted below) appears to have taken up the grub gauntlet (I counted no less than thirty instances of the word in his latest work, Sentiment and Substance).
