This is an excellent book! It is so full of wisdom that, paradoxically, it's almost a challenge to read and process all of its insight. Piero Ferrucci, the author, is a practicing psychiatrist in Italy who uses kindness as a metaphor to explore the qualities/aspects that make a fulfilling life. In the process, he examines various aspects of kindness - from Honesty to Forgiveness to Trust to Humility to Service, etc. - including how and why they are relevant, how we should conceive of and use them in our own lives, etc. In so doing, he takes on a journey of who we all wish we could and should be, often approaching familiar subjects in new and unexpected ways.
For example, Ferrucci's take on Patience begins with an Ethiopian folk tale, moves on to a rumination of how difficult people can be softened/turned around by unexpectedly kind treatment, then reflects on the modern tendency to "leave our souls behind" and engages in an extended consideration of the concept of time, including a very interesting application of Buber's I-Thou/I-It rubric. Along the way, he challenges us thoughtfully to examine what we believe both generally and about ourselves and then shows us alternatives that will make us both more kind specifically and better people generally.
There are a few interesting juxtapositions in the book that lessen its impact somewhat, but these are minor in both extent and consequence. For example, in an aside in the Memory chapter, he recounts a story of being asked for directions by a woman seeking food for her child, but his response - he judges her and then chooses not to assist her - seems less than kind. This proves that the author is human, but, thankfully, is such a rare occurence that it is noteworthy only because it contrasts so greatly.
In summary, I highly recommend this book to anyone and everyone - we can all benefit from its piercing insights and its very helpful guidance. Ferrucci has written a classic. I, for one, value it so highly that I intend to read it again from time to time to keep its lessons fresh and top of mind.
