An interesting manual
I read this book a number of years ago, and noticed that it had been reissued. It originally appeared in 1934. Admittedly it does show its age, in both style (which tends to be a bit, er, "floral") and its research advice (pre-computer). Nevertheless, I was not disappointed in re-reading it. Sertillanges is not of that hardheaded "How to Organize your Life and your Time" school, but directs himself to encouraging the intellectual life for its own sake -- a rare encouragement in a time, such as ours, in which knowledge is encouraged only insofar as it facilitates the acquisition of something other than the knowledge itself.
