Edmund Husserl's Logical Investigations (1900–1901) ranges over some 1000 pages. (Husserl 1968, 1970.) Arguably his magnum opus, certainly the foundation for all his subsequent writings, this daunting work looks like a patchwork of ideas on a lot of largely independent philosophical themes. For a hundred years most readers have taken and used it in that way. Certainly I did for many years. (Particular issues from the Investigations are pursued for instance by : Mohanty 1982 and Willard 1984 on antipsychologism in the Prolegomena; Sokolowski 1974 and Simons 1995 on language in Investigation I; B. Smith ed. 1982 and Fine 1995 on the ontology of part/whole in Investigation III; Bar-Hillel 1956 on logical grammar in Investigation IV; Smith and McIntyre 1982 on content and intentionality in Investigation V ; Willard 1995 and Ff llesdal 1999 on knowledge and intuition in Investigation VI.)
