Through the combined effects of certain natural facts (connected with the passage of time), institutional acts (performed at various points within the university system) and bonds offriendship (forged over quite a number ofyears ofacademic life), I have lately become an occasional writer of forewords. It is certainly not a kind of work that dis pleases me; but it would be too much to say that I have learned to do it with ease. Quite to the contrary! Writing a foreword is, it seems to me, an example ofa rather complex action (al though, of course, much less complex than writing the book it accompanies). Infact, it is not even an action; it is rather an activity, carried out over a more or less prolonged period of time and typically including something like the following stages: deciding to write the foreword; carefully reading the book; taking notes; thinking about what would be appropriate aspects to be mentioned; sketching an outline; writing a first draft by hand; writing several corrected versions; typing the last ofthem into the computer; dis tributing it to several colleagues to see how they like it; correcting the text once more; sending it to the author of the book; delivering it to the publisher. Ineach of these ac tions (leaving aside for a moment purely mental actions such as thinking) we can in turn distinguish several components. These are, basically: bodily movements, intentions, and (intentionally or unintentionally produced) changes in the world.
