This is not a book for a Christian to read. The book is basically the ramblings of the author. At about 7% of the book, the author decides to attack the Bible, Christianity, and basically everything to do with religion.
Practical Psychology is not a book about the inner-workings of the mind. It touches on the environment, politics, economics, and several other things all without any specific thought expressed.
I fought my way through a large part of this book thinking that the author had experienced "Mind Puke."
