On Strength 

What is strength? Is it as obvious as it seems? Why do you need it? This book explores and ponders various facets of strength in a philosophical dialogue that probes the meaning of character and values, what is worth fighting for–and why; what it means to be a true friend; how to know when it’s right to stand up to others; what it means to be strong and how to find and train our own inner strength.
