The catechism itself is good, obviously, but the commentating author himself is woefully worldy, short sighted, and gullible. Very Victorian too, such as in saying nothing about the vast duties of parents towards children, but much about the reverse. Very full of Science worship, and silliness, such as repeatedly speaking as if Issac Newton is some great spiritual authority because he used the word 'God' with respect (actually referring to himself). Why should I laud some occultist? Why? Because he's a famous 'scientist'? Famous witch, more like.
Also makes the classic Lukewarm Catholic telltale error of referring to people as 'mere mortals' in comparison to saints. No saint or advanced Catholic could or does make such a statement.
