This week’s speaker certainly gave us food for thought. Lindsay Gilligan PSM has well over 40 years’ experience as a geologist with a career that has focused on the geology of mineral resources and fostering mineral exploration and discovery in NSW. He finished his career in 2009 as Chief Government Geologist.
Following his retirement Lindsay joined with Frank Oakes and David Atkinson in establishing the Hunter Valley Socratic Society which has proved to be a highly successful forum for an eclectic bunch to discuss many and varied philosophical and social issues. This was the focus of today's presentation with Lindsay explained the meaning of Philosophy - telling us that it’s about thinking. He also spoke of past philosophers and the impact that such as Plato and Aristotle have had on the way people have thought about Christianity over the years.
Lindsay also mentioned the Hunter “Pi in the Sci” society that has a focus on STEM (Science, Technology, Engineering and Mathematics) and is instrumental in raising funds to support the tutoring of individual HSC students in STEM subjects.
