He also was keen to see superstition and ant-scientific attitudes to disappear. Part of being a Fellow of ISCAST is to pursue this in line with a Christian world view. After all, if God is creator then he is neither superstition nor magic but shapes the universe such that our connection with the universe is both our understanding of it and our relationship to its creator.
