If you found it, give him or her the attribution, which is why he or she came here.
Piratejo, when you have a quote, and you type it exactly (or even just a portion of it) into the search window at a reputable search engine, if the text of your quote is correct, the answer will be returned to you.
So, for example, if i type "solitary, poor, nasty, brutish and short" into the Google search window, it returns 39,700 results. The first result on that page is a link to
Leviathan, by Thomas Hobbes, and it has the complete text of Chapter XIII, which includes this sentence:
Quote:In such condition there is no place for industry, because the fruit thereof is uncertain: and consequently no culture of the earth; no navigation, nor use of the commodities that may be imported by sea; no commodious building; no instruments of moving and removing such things as require much force; no knowledge of the face of the earth; no account of time; no arts; no letters; no society; and which is worst of all, continual fear, and danger of violent death; and the life of man, solitary, poor, nasty, brutish, and short. (emphasis added)
I got that result because i had an exact quote, and merely a small portion of it. I also intentionally typed the sequence of words incorrectly, and got even more results, and i also got the exact, correct result, as above, as the third link on that page. Often, all you have to do is come close.
I typed your quote exactly into a Google search window, and didn't get a coherent answer. I suggest that your quote is incorrect, and sufficiently incorrect that even Google can't sort it out. Alternatively, it is from a source sufficiently obscure that it doesn't appear online. What was the source of your quote?
