Know Yourself Through the Four Temperaments
This is my go-to book for a brief introduction to the Four Temperaments from a Catholic perspective. This quick read was written by a priest and first published in 1934.
This book is rated ❤️ because I don’t own this edition. My copy was published by the Pallottine Fathers of Milwaukee, Wisconsin, copyright 1962, reprinted in 1994, without an ISBN number.
