Exercises for a Third Eye

Dick Hillenius wrote on biological subjects with an infectious enthusiasm and single-mindedness that are rare in research scientists. He was passionate about frogs, toads, and chameleons, but wrote with equal facility about music, literature and the visual arts. It would not have taken much for him to become a composer. He was a great sceptic, convinced that the whole of science is hypothetical and that the truth keeps shifting. He conducted mental experiments, broached new themes in an original way and was always keen to connect what was still unconnected.
