 Use the form above to search for documents in this website containing specific words or phrases. Type your query and press Search button. BE SURE TO SPELL CORRECTLY (it is no use, for instance, searching for “hypothisis”)! Note that I usually prefer American to British spelling of English.This search facility seems based on whole words; parts of words won’t do. If a noun does not work, try the corresponding adjective or verb; or vice-versa; e.g. if “Freud” yields nothing or not enough, try “Freudian”. Preferably, keep your query simple. Try single words rather than complex phrases. e.g. ask for “adduction” rather than for “the definition of adductive argument”.More often than not, you are likely to be offered too many hyperlinks in response to your query.For this reason, you may find it worthwhile searching through one book at a time, using the box on the right hand side marked ‘site’ to select the book. But note that you can also “refine” your search in successive stages.
Sometimes, the best way to search for a specific topic in The Logician is to look in the General Sitemap, or in the more detailed tables of Contents of the various books (use the buttons at top and on the left to find those). Once there, you can use your browser’s “edit/find” facility; or scroll down looking for the chapter and section most likely to contain the information you need. (For example, if you seek the definition of ‘logic’, it is hopeless to search for that word, since it is used in almost every page! Rather, go to Future Logic, chapter 1, section 1, and you will likely find a good first definition.)Try also the Shortcuts below to various topics.
