For an eventless world is a world without change, and a world without change is a world without time, with all the ensuing consequences (of imortality and eternity :). No event, no change; no change, no time; no time, no human history, memory and experience, i.e., no both human life and mental life. Both an eventless world of objects, and an objectless world of events are poor constructs. It's like constructing an eventless web of objects, and an objectless web of events. When somebody doubts if events exists, if there are any events, he actually doubts if anything in the world happens at all: the Olympics, festivities, sporting events, his birth, dates and marriage, and possible death. Re. literature on Events. It is vast, http://books.google.com/books?q=Events. I recommend to start from an anthology on Event, studying its ontology, semantic, logics and NL descriptions, very useful to read for all the semwebers, http://books.google.com/books?id=PZ7WAAAAMAAJ&q=Events&dq=Events. The book consists of five Parts: Events in Semantics; The Nature of Events; Identity and Individuation; Cause, Space, and Time; Events and Processes. An integrated ontological account of change (and event) is given in the Reality book, http://books.google.com/books?id=mmVjIylBWlEC&pg=PT156&dq=reality+and+universal+ontology#v=onepage&q=&f=false Have also to mention, there is an emerging multi-billion business, called Event Management Industry: dealing with all sorts of international social events, festivals, ceremonies, sporting events, mass media events, summit meeting of all sorts and kinds. Apropos, there are many festivals, arts, film, literary, music, religious, science, but an Internet/Web Festival :).
