Good summary and explanation of Van Til's thoughts on how evidences are to be used in Christian apologetics. At least it is a good summary as far as I can tell from what I have read of Van Til. As always, Cornelius Van Til is an incredibly confusing writer, and I would say that apologetics would be better off moving past him, except that he has valuable thoughts on Christian philosophy and worldview that directly affect how one gives a valid defense of Christianity. But as difficult to understand as some of Van Til's work is, his arguments lend themselves well for this type of book, where quotes of Van Til are interspersed with explanations and clarifications of what he is saying. A drawback of this book is that, while the author explains theoretically how evidences should be used, it is still not clear practically how a presuppositional apologist should use evidences in anything like an actual conversation/debate.
