​In a lecture, delivered in Vienna in 1894 and dedicated "to the academic youth of Austria-Hungary", Franz Brentano outlined four phases of advance and decline which he saw as providing the key to the understanding of the history of Western philosophy. In the first cycle, in antiquity, the initial advancing phase culminated in the work of Aristotle, and was followed by three phases of decline​,​ terminating in the irrational mysticism of the Neo-Pythagoreans. These four phases then repeated themselves: in the Middle Ages, ​beginning with Aquinas and ​ending with the "learned ignorance" of Nicholas of Cusa​;​ and then in the modern period, ​beginning with Bacon and reaching its low point in the work of Kant, Fichte, Schelling, and Hegel. In the contemporary era we are currently witnessing the end of ​the fourth cycle in the work of (for example) Derrida, Rorty; but also the beginnings of a new, fifth cycle, which is described in the talk. (Presented at the conference Consequences of Realism, Rome, May 4-6, 2014.)

  1. 1. The Fifth Cycle of Philosophy Barry Smith
  2. 2. Brentano’s Four Phases In a lecture, delivered in Vienna in 1894 and dedicated "to the academic youth of Austria- Hungary", Franz Brentano outlined four phases of advance and decline which he saw as providing the key to the understanding of the history of Western philosophy.

  4. 4. First Cycle Thales to Stoicism and Pyrrho, Neo-Pythagoreans, Aristotle Epicureanism Eclectics Neo-Platonists 4 Aristotle empirical wonderment
  5. 5. Second Cycle Rediscovery of Scotism Ockham, Lull, Aristotle by Augustine Nominalists Nicholas of and Early Scholastics Cusa 5 Aquinas learned ignorance
  6. 6. Third Cycle Bacon Christian Wolff Hume Berkeley, Fichte Descartes Reid Schelling, Hegel Leibniz, Locke Kant 6 grounding knowledge on blind prejudices

  11. 11. 11 The Birth of Psychology 1874: Brentano publishes Psychology from an Empirical Standpoint Vera philosophiae methodus nulla alia nisi scientiae naturalis est. 1879: Wundt establishes world’s first psychological laboratory at the University of Leipzig 1883: Wundt establishes a journal entitled Philosophische Studien, to publish the results of his laboratory experiments
  12. 12. 12 The Birth of Psychology 1889: First International Congress of Psychology; Meinong founds Laboratory of Psychology in Graz 1892: American Psychological Association founded, with 42 members 1894: Stumpf becomes professor of philosophy in Berlin with explicit task of establishing an institute of psychology 1907: Twardowski founds first psychological laboratory in Poland

  14. 14. Philosophy gives birth to mathematical logic and computer science Frege Gödel Russell Tarski Whitehead Turing 14
  15. 15. Derrida Rorty Judith Butler 15 Each final phase of decline, with its ultimate collapse into nonsense and jokes, gives rise to the call for a new phase of renewal.
  16. 16. You are now here 16 Derrida Rorty Butler
  17. 17. The Fifth Cycle Phases of renewal are associated with a new focus on empiricism, on rigour and clarity, a new scientific relevance of philosophy, 17

  20. 20. 20 why were disciplines such as physics or psychology … founded? feelings of chaos, sectarianism, superficiality, deadendedness, triviality inside philosophy philosophy goes round and round in circles forever re- re-re-re-re-explaining Kant’s theory of apperception new methods for tackling philosophical problems also address extra-philosophical concerns empirical results increasing cross-disciplinary collaboration between philosophy and extra-philosophical disciplines

  26. 26. Ontology (philosophy) (Synonym of ‘metaphysics’) The science of being. A theory of the types of entities existing in reality, and of the relations between them, for example between basic and non- basis entities. 26
  27. 27. Ontology (science) The science which develops theories of the types of entities existing in given domains of reality, and of the relations between them such theories are represented as computational artifacts called ‘ontologies’ which are used to describe heterogeneous data in consistent ways to support comparison and integration 27
  28. 28. World’s first ontology scientist Cornelius Rosse (born in Hungary in 1932, studied Aristotle in the Jesuit seminar in Budapest, used his knowledge of Aristotle to create the Foundational Model of Anatomy (FMA), the first philosophically rigorous biological ontology Rosse draw on his knowledge of Aristotle to create the Foundational Model of Anatomy (FMA), the first philosophically rigorous biological ontology

  35. 35. 35 Ontology (science) is not a job for software engineers but it is not a job for philosophers, either, e.g. where ontology is playing an increasing role in supporting interdisciplinary communication between human beings – for example in improving communication between Federal government departments
  36. 36. 36 Typical reasons for founding a new discipline feelings of chaos, deadendedness, triviality inside the mother discipline new methods for tackling problems of the mother discipline new kinds of empirical methods and results increasing need for cross-disciplinary collaboration – e.g. marked by multi- authorship
