This mode searches for entries containing all the entered words in their title, author, date, comment field, or in any of many other fields showing on OPC pages.
Surname
This mode searches for entries containing the text string you entered in their author field. Note that the database does not have first names for all authors, so it is preferable to search only by surnames. If you search for a full name or a name with an initial, enter it in the format used internally, namely the "Lastname, Firstname" or "Lastname, F." format.
Advanced
This mode differs from the all fields mode in two respects. First, some information not publicly available on the site is searched, e.g., abstracts and excerpts gathered by the crawler, which are not always accurate but can help broaden one's search. Second, you may prefix any term with a '+' or '-' to narrow the search to entries containing it or not containing it, respectively. Terms which are not prefixed by a '+' are not mandatory. Instead, they are weighed depending on their frequency in order to determine the best search results. You may also search for a literal string composed of several words by putting them in double quotation marks (").
Note that short and / or common words are ignored by the search engine.

Although the colors at the zenith and the horizon are obviously distinct, nowhere in the sky can one see any color borders, and every sufficiently small region of the sky is made up of regions that all seem to be of the same color
Abstract: The idea that we have special access to our own mental states has a distinguished philosophical history. Philosophers as different as Descartes and Locke agreed that we know our own minds in a way that is quite different from the way in which we know other minds. In the latter half of the 20th century, however, this idea came under serious attack, first from philosophy (Sellars 1956) and more recently from developmental psychology.1 The attack from developmental psychology arises from the growing body of work on
