Grote's powerful defence of Thrasyllus' canon should have taught us at least not to reject lightly any dialogue which, like the Hippias Maior, is there classed as genuine. The burden of proof lies with those who attack our dialogue. Raeder, Ritter, and Apelt consider it to be genuine, while Ast, Jowett, Horneffer, and Röllig declare against it, as also Gomperz, Zeller, and Lutoslawski.
