Les leçons de ce volume IV se répartissent en quatre ensembles, appartenant à divers moments de la carrière de Bergson :
-- Cours sur Plotin, École normale supérieure, probablement vers 1898-1899 (manuscrit conservé à la bibliothèque Victor Cousin) -- Cours d'histoire de la philosophie grecque, Khâgne, Lycée Henri-IV, année scolaire 1894-1895 -- Leçons sur l'École d'Alexandrie, Lycée Blaise-Pascal, Clermont-Ferrand, probablement vers 1884 -- Le cahier noir, Université de Clermont-Ferrand, 1884-1885
Ce volume, comme les trois précédents, espère contribuer au renouveau des études bergsoniennes. Les deux premiers volumes de Cours ont fourni l'essentiel de l'enseignement de Bergson sur les diverses matières philosophiques (psychologie et métaphysique, morale et politique), les deux derniers permettent d'avoir une idée précise de son enseignement en histoire de la philosophie, moderne et contemporaine pour le Cours III, grecque pour ce volume IV.
Popular and accessible works of French philosopher and writer Henri Louis Bergson include Creative Evolution (1907) and The Creative Mind (1934) and largely concern the importance of intuition as a means of attaining knowledge and the élan vital present in all living things; he won the Nobel Prize of 1927 for literature.
Although international fame and influence of this late 19th century-early 20th century man reached heights like cult during his lifetime, after the Second World War, his influence decreased notably. Whereas such thinkers as Maurice Merleau-Ponty, Jean Paul Sartre, and Lévinas explicitly acknowledged his influence on their thought, Bergsonism of Gilles Deleuze in 1966 marked the reawakening of interest. Deleuze recognized his concept of multiplicity as his most enduring contribution to thinking. This concept attempts to unify heterogeneity and continuity, contradictory features, in a consistent way. This revolutionary multiplicity despite its difficulty opens the way to a re-conception of community, or so many today think.
I corsi che il professor Bergson ha tenuto sulla filosofia greca, o più specificatamente – in due casi – sugli Alessandrini e Plotino.
Tutti i testi si trovano a metà fra la pubblicazione di Materia e memoria e L'evoluzione creatrice. Ci dànno quindi il polso della preparazione e della genealogia, per usare un termine molto in voga, della grande opera del 1907 di Bergson.
I corsi sono chiari e utili, quindi. Tuttavia vi è un magrissimo commento da parte dei curatori, un apparato di note molto superficiale.
