Sam Butchart wrote an entry on Critical Thinking for the Companion to Philosophy in Australia and New Zealand. I was pleased to be among three philosophers Sam discussed in a little detail, the others being Charles Hamblin and Michael Scriven.
It turns out that all three were educated at the Geelong Grammar School and then at the University Melbourne. Go figure.
