"Hume's 
    section entitled 'Of Scepticism with regard to the Senses' is his principal 
    discussion of objectivity-concepts. It is extremely difficult, full of mistakes, 
    and-taken as a whole-a total failure; yet its depth and scope and disciplined 
    complexity make it one of the most instructive arguments in modern philosophy 
    . One philosopher might be judged superior to another because he achieved 
    something of which the other was altogether intellectually incapable. By that 
    criterion Hume surpasses Locke and Berkeley-because, and only because, of 
    this one section."
