Feasts of literature

A favorite passage of mine, from Johnson's Preface to the Dictionary, one that has retained its charge for me even through its perhaps overly frequent quotation in random contexts:

To have attempted much is always laudable, even when the enterprize is above the strength that undertakes it: To rest below his own aim is incident to every one whose fancy is active, and whose views are comprehensive; nor is any man satisfied with himself because he has done much, but because he can conceive little. When first I engaged in this work, I resolved to leave neither words nor things unexamined, and pleased myself with a prospect of the hours which I should revel away in feasts of literature, the obscure recesses of northern learning, which I should enter and ransack, the treasures with which I expected every search into those neglected mines to reward my labour, and the triumph with which I should display my acquisitions to mankind. When I had thus enquired into the original of words, I resolved to show likewise my attention to things; to pierce deep into every science, to enquire the nature of every substance of which I inserted the name, to limit every idea by a definition strictly logical, and exhibit every production of art or nature in an accurate description, that my book might be in place of all other dictionaries whether appellative or technical. But these were the dreams of a poet doomed at last to wake a lexicographer. I soon found that it is too late to look for instruments, when the work calls for execution, and that whatever abilities I had brought to my task, with those I must finally perform it. To deliberate whenever I doubted, to enquire whenever I was ignorant, would have protracted the undertaking without end, and, perhaps, without much improvement; for I did not find by my first experiments, that what I had not of my own was easily to be obtained: I saw that one enquiry only gave occasion to another, that book referred to book, that to search was not always to find, and to find was not always to be informed; and that thus to persue perfection, was, like the first inhabitants of Arcadia, to chace the sun, which, when they had reached the hill where he seemed to rest, was still beheld at the same distance from them.
