Excellent brief tour through the history of contributions to civilisation from Catholics, Church-supported organisations and the Church itself. It covers not just the arts -as would be expected- but charity, law, language, science and more.
Did you know, for instance, that the Church created the university system across Europe in the early Second Millennium, and was responsible for the first schools? That Nicolaus Copernicus was a Catholic priest? That Galileo's daughter chose to become a nun? That Gregor Mendel, the founder of the science of genetics, was a monk? That Georges Lemaître, the originator of Big Bang Theory, was a Catholic Priest? Along with more on science and philosophy we see that the Church is responsible for the nature of the legal system across much of the world, and that our Western concepts of individual persons and human dignity originate with Catholicism.
In addition to its intended purpose for instructing those interested in becoming Catholics, this makes an superb precis for the general reader. But I must end with a caution about using this for apologetics.
If someone argues against Christianity that it has been responsible for a lot of evil in history, it would be fatal for the Christian to respond by regurgitating the facts from this pamphlet. Instead of accepting the antagonist's terms -upon which he will never be convinced- the Christian must dispute them. It is not Christianity that has been responsible for evil in history, but particular *people and institutions*, some of whom happened to be affiliated to Christianity, or even cited the religion as an excuse for their actions. That they have done bad things is not in question, but it does nothing towards proving that Christianity is false. Likewise, the Christian must not, on pain of inconsistency, approach the non-Christian and argue for the truth of Christianity based upon the good things that particular Christians and Christian institutions have done in the past.
