1991 Wittgenstein—On Certainty
The only book that almost made the list three times—in three different decades and for three different reasons.
In 1983 it offered a deeper and and more thoughtful approach than G. E. Moore’s “solution” for the problem of certainty. Which for me was a welcome antidote to the dominate Anglo-American materialism and “common sense” approach to philosophy I experienced at school.
In 1991 it presented a deeper and more thoughtful alternative to the shallow and superficial world of fashion, advertising and photography where I spent almost every waking hour.
In 2004 It provided an introduction to the Goethe Institute Philosophy Group which has proved to be one of the great joys of my life providing a better philosophical education than I ever got at school and more interesting social connections than I ever found anywhere.
