Philosophy and Botany


A memorial symposium for Ivar Segelberg was held in Gothenburg on September 12-13, 2008. Here is the link to the conference program. It includes a comprehensive background and a list of contributors.

This page is a brief pictorial report from the meeting. All pictures were taken by Martin Filin Karlsson. They are presented in approximate chronological order. If no affiliation is stated for the speakers, they are from the university of Gothenburg (or Göteborg, as we say in Göteborg).

Then, Herbert Hochberg from the University of Texas in Austin led us into the intricacies of Ivar Segelberg's theory of relations. Hochberg first met Segelberg around 1960.

Christer Svennerlind gave the last presentation on Friday but alas, there is no picture from his lecture (which also concerned Segelberg's ontology)

Here is the organizing committee: Christer Svennerlind and Helge Malmgren

Day 2 – Saturday, September 13

On Saturday morning, Helge Malmgren gave an overview of Ivar Segelberg's botanical work and reported from a botanical voyage to Sardinia in 1964. Then, professor Sandro Pignatti, University of Rome, lectured about principles of botanical taxonomy and told us about the great influence that Ivar Segelberg had on his work with the Flora d'Italia (1982).


Here, Erika Pignatti Wikus and Sandro Pignatti are discussing African botanical folk taxonomy with Christina Thornell. Dag Westerståhl to the left.
