A generous and elevated mind is distinguished by nothing more certainly than an eminent degree of curiosity - Samuel Johnson

It is not by comparing line with line, that the merit of great works is to be estimated, but by their general effects and ultimate result. It is easy to note a weak line, and write one more vigorous in its place; to find a happiness of expression in the original, and transplant it by force into the version: but what is given to the parts may be subducted from the whole, and the reader may be weary, though the critick may commend. Works of imagination excel by their allurement and delight; by their power of attracting and detaining the attention. That book is good in vain, which the reader throws away. He only is the master, who keeps the mind in pleasing captivity; whose pages are perused with eagerness, and in hope of new pleasure are perused again; and whose conclusion is perceived with an eye of sorrow, such as the traveller casts upon departing day.

Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information upon it. When we enquire into any subject, the first thing we have to do is to know what books have treated of it. This leads us to look at catalogues, and at the backs of books in libraries.

Fears of the brave, and follies of the wise!
From Marlb'rough's eyes the streams of dotage flow,
And Swift expires, a driv'ler and a show.
