Incidentally, I should warn you that in
Mathematics for the Nonmathematician, Kline mounts a wrong-headed attack on Augustine in Chapter 1, page 1, which takes the form of this quotation:
One can wisely doubt whether the study of mathematics is worth while and can find good authority to support him. As far back as about the year 400 A.D., St. Augustine, Bishop of Hippo in Africa and one of the great fathers of Christianity, had this to say:
The good Christian should beware of mathematicians and all those who make empty prophecies. The danger already exists that the mathematicians have made a covenant with the devil to darken the spirit and to confine man in the bonds of Hell.
Perhaps St. Augustine, with prophetic insight into the conflicts which were to arise later between the mathematically minded scientists of recent centuries and religious leaders, was seeking to discourage the further development of the subject. At any rate there is no question as to his attitude.
Unfortunately, there is almost nothing correct here. The latin word
mathematici cannot, given the context in which the word appears, be translated "mathematician". Instead, it must be translated "numerologist". The correct translation of the Augustine passage reads thus:
For this reason, the good Christian should beware not only numerologists, but all those who make impious divinations, above all when they tell truth. Otherwise, they may deceive the soul, and ensnare her in a pact of friendship with demons.
See here for a reference. So you see that Augustine cannot be made out to object to mathematics.
In addition, the way Kline refers to the conflict between the mathematically minded scientists and the religious leaders makes it seem like the conflict was between science and religion, whereas it was not. This is neither the time nor the place for this debate, so I won't go into it. I just wanted to warn you about some of the inaccuracies. It's still a really good book on mathematics.
