How much did this guy read???

Hello brothers and sisters in Christ! I have recently taken up reading Herman Bavinck’s Reformed Dogmatics. I’m currently about halfway done with volume I, and I am perplexed by something; How much time per day did this man read? His citations are overwhelming! It seems like he read every theological book in every language since the first century.

Is this something James Eglinton addresses in his biography on Bavinck? I am genuinely interested in the time this man spent in his study to have so much information at his disposal.

-Also, anyone who has read/is reading Reformed Dogmatics, feel free to chime in about your favorite parts. I do not personally know anyone who has read it in its entirety, so I’ll take any discussion of talking points I can get. Have a blessed day!
