The essays presented in this collection were written over a long period. The first two : "On the Classification of Verbs and Actions" and "On von Wright's Theory of Action" constitute steps in my preparation for the book Events, Actions, and Ordinary Language, Lund 1977. Much of the contents of the former paper was carried over to the book, whereas the analyses in the latter paper were more or less completely left out. These papers have not been published before . "On Various Forms of Interaction" is a development of soroe ideas in Events, Actions, and Ordinary Language. This paper was previously published in Swedish in Henschen-Dahlqvist A-M ed. Filosofiska smulor, Festskrift tillägnad Kon rad Marc- Wogau på hans 75-årsdag, Uppsala 1977. "...
