This book for me was a debate about the choices a Man must make when he chooses a mode of life, a life that is self sufficient, isolated, avoiding the conflicts of life's struggle, or a life that is in a constant battle with his contemporaries, his leaders, but collectively is a progress for the race. I found the arguments on both side to be just in their own thought. That man's action should not be judged by his individual outcome but rather by the collective outcome of the race. It should also be kept in mind that not every man can lead a life that will directly impact the race, and hence neither extremes should be imitated everyone, it is only that man should choose his niche and yet contribute to the progress of mankind, lest he not waste his skills. Man should also devote his time and energy to the skill that will bring out the maximum potential within himself thereby contributing to the well being of society in the best possible way.
There is also a talk about whether Man should devote his time to leading the race or helping the destitute, a direct correlation to which is, A Man should not be bogged down by the ailing part of his body but rather strengthen his mind to lead his will. Seeing the poor does make the sunshine unpleasant, but maybe leading their mind is the broader picture for humanity rather than softening the heart seeing their penury.
I have found this book very enriching especially as I was in a crossroad of my own.
