Cyril Edwin Mitchinson Joad was an English philosopher and broadcasting personality. He is most famous for his appearance on The Brains Trust, an extremely popular BBC Radio wartime discussion programme. He managed to popularise Philosophy and became a celebrity, before his downfall in the Train Ticket Scandal of 1948.
My edition is a reprint of 1947 edition, so "modern" in the title may be misleading now. The book primarily focuses on the impact of certain scientific discoveries, including some pseudoscientific concepts such as ghost mediums, on philosophy.
Only utility from the book will be historic in nature.
