The present publication is a continuation of two earlier series of chronicles, Philosophy in the Mid-Century (Firenze 1958/59) and Contemporary Philosophy (Firenze 1968), edited by Raymond KJibansky. As with the earlier series the present chronicles purport to give a survey of significant trends in contemporary philosophi­ cal discussion. The time space covered by the present series is (approximately) 1966-1978. The need for such surveys has, I believe, increased rather than decreased over the last years.

Surveys of the present kind are a valuable source of knowledge of this complexity and may as such be an assistance in renewing the understanding of one's own philosophical problems. The surveys, it is to be hoped, may also help to strengthen the Socratic element of modem philosophy, the dialogue or Kommu nikationsgemeinschajt. So far, four volumes have been prepared for the new series.
