Thanks for the comment. I'm delighted to find Rand despised it. So do I.
I suppose Carnegie's books may be of value for developing children, or recovering sociopaths in a parole program, people that need to start considering the feelings of others.
And I agree that one should know when to cut losses, to stop throwing good money after bad, and I could rant some more about the "lessons", and how they can be twisted.
But that is my point about the Carnegie' philosophy. Its a bunch of concrete principles, like the 10 commandments. Don't lie, steal, kill, et. unless there are *special exceptions*. You are lying, cheating or killing the enemy of the leader, people, or clergy.
And what is the principle behind making exceptions to the rules? That some combination of tradition/entrenched power, authority, popular consensus and/or sentiment should be the substitute for one's own reason. Usually causing the individual to self-sacrifice to the collective or leader, or worse, mere tradition.
That is what Rand denounced so often, why she had to base her philosophy starting from the axiom existence exists. She well said such concrete-bound philosophies were like a bunch of lumber thrown in a tangled pile of contradiction and conflict, while objectivism is like a geodesic dome.
Again, I think it is a mistake for students and practitioners of Objectivism to waste time and confuse themselves with Carnegie. In the book "How to start living..." Carnegie admonishes re-reading the book, like a Bible, applying the principles and considering them. You've only got so much time. You're going to make associations and evaluate your experience and behavior according to principles. You want to waste your time on concrete-bound rule-sets, or a self-consistent hierarchical value structure that necessitates checking context and premises?
Jamming your mind with confusing data can be as bad as believing lies. It separates you from truth and achievement. Motorola wanted their employees to take in the secular religion for a reason. To make us good little toadies, good little worker-drones.
