Programme subject to change -

One change is the speaker on Grammar. Unfortunately Leon Conrad will be unable to attend because of family circumstances. Fortunately John Thomson, author of "‘The Experience of Thinking from Plato to Buber." is able to take his place.

Mary-Anne Paterson has also unfortunately needed to bow out. Again fortunately, Izumi Maeda, art teacher and therapist, is able to join us and will offer the wonderful opportunity to paint (in the 3 consecutive sessions), the day rainbow, the night rainbow and the zodiac rainbow. (Max. 7 people)
