Great wits are sure to madness near allied, and thin partitions do their bounds divide. - John Dryden

To begin then with Shakespeare; he was the man who of all Modern, and perhaps Ancient Poets, had the largest and most comprehensive soul. All the Images of Nature were still present to him, and he drew them not laboriously, but luckily: when he describes any thing, you more than see it, you feel it too. Those who accuse him to have wanted learning, give him the greater commendation: he was naturally learn'd; he needed not the spectacles of Books to read Nature; he look'd inwards, and found her there. I cannot say he is every where alike; were he so, I should do him injury to compare him with the greatest of Mankind. He is many times flat, insipid; his Comick wit degenerating into clenches; his serious swelling into Bombast. But he is alwayes great, when some great occasion is presented to him: no man can say he ever had a fit subject for his wit, and did not then raise himself as high above the rest of the Poets,

Better shun the bait, than struggle in the snare.

But wilde Ambition loves to slide, not stand;
And Fortunes Ice prefers to Vertues Land
