Neitzsche’s saying xianity is “slave morality” described my Catholic father and his father well. My mother’s having been raised a Methodist helped me escape RC slavery.

Critique without understanding is useless. Marx provided both And the Marxist analysis of religion is consequently more useful. Marxist governments have led the some of the greatest growth in atheism.

Nietzsche carved out his place in the history of philosophy and is ranked with eminent philosophers. Some have said that Nietzsche is a philosopher's philosopher. He certainly had a sense of humor when you consider his statement: "In heaven all the interesting people are missing."

Some of his writing is impressive and some not. You have to understand his times and where he came from to try and understand him. Many today still fight his idea of "god is dead" by making stupid and ignorant movies on the subject. For example, many disagree with me when a famous modern non-believer turns to god because if he did not he would lose his wife and children. Lee Stobel is one such man that comes to mind as I write.

I have difficulty understanding what he is really talking about but from what I understand, I do like his writing. He has great one liners. If you like it, you might also consider other existential philosophers. Ernest Becker won a pulitzer prize for his denial of death. I would consider Viktor Frankl's book to be based on existential philosophy too. Sheldon Solomon's Worm at the core summarizes many of the arguments made by these philosophers, providing empirical data to support the claims

I don't think he covered anything to do with religion.

Religion ... pure and faultless is this: to help widows and orphans in need and avoiding worldly corruption. James 1:27

Where does he say anything about helping widows and orphans?

I do not know who he is.

Don't agree with them.

I have read a lot of his work. Nietzsche is not easily understood, people who do not take the time to read and absorb what he writes usually misunderstand him, and usually not in a small way. But for the people that do understand, it is really a mind-expanding experience. A good book to help is Hiking With Nietzsche. On the positive side, Nietzsche was every bit as brilliant as they say, his work dazzles with it.
My favorite example is his "The Sage as an Astronomer: "If you still see the stars as something above you, you lack the eye of knowledge." There are many others.

"Even under the influence of the narcotic draught, of which songs of all primitive men and peoples speak, or with the potent coming of spring that penetrates all nature with joy, these Dionysian emotions awake, and as they grow in intensity everything subjective vanishes into complete self-forgetfulness. In the German Middle Ages, too, singing and dancing crowds, ever increasing in number, whirled themselves from place to place under this same Dionysian impulse. [...] There are some who, from obtuseness or lack of experience, turn away from such phenomena as from "folk-diseases," with contempt or pity born of consciousness of their own "healthy-mindedness." But of course such poor wretches have no idea how corpselike and ghostly their so-called "healthy-mindedness" looks when the glowing life of the Dionysian revelers roars past them." Friedrich Nietzsche

"Those you cannot teach to fly, teach to fall faster." . . Friedrich Nietzsche

"If you gaze long into an abyss, the abyss will gaze back into you." Friedrich Nietzsche

"We have art in order not to die of the truth." Friedrich Nietzsche

When a hundred men stand together, each of them loses his mind and gets another one. (Friedrich Nietzsche)

"All things are subject to interpretation - whichever interpretation prevails at a given time is a function of power and not truth." - Friedrich Nietzsche

From the Preface to Nietzsche's The Birth of Tragedy:
"...Perhaps the depth of this antimoral propensity is best inferred from the careful and hostile silence with which Christianity is treated throughout the whole book -- Christianity as the most prodigal elaboration of the moral theme to which humanity has ever been subjected.... Behind this mode of thought and valuation... I never failed to sense a hostility to life -- a furious, vengeful antipathy to life itself.... Christianity was from the beginning, essentially and fundamentally, life's nausea and disgust with life, merely concealed behind, masked by, dressed up as, faith in "another" or "better" life. Hatred of "the world," condemnations of the passions, fear of beauty and sensuality, a beyond invented the better to slander this life, at bottom a craving for the nothing, for the end, for respite, for "the sabbath of sabbaths" -- all this always struck me, no less than the unconditional will of Christianity to recognize only moral values, as the most dangerous and uncanny form of all possible forms of a "will to decline" -- at the very least a sign of abysmal sickness, weariness, discouragement, exhaustion, and the impoverishment of life. For, confronted with morality (especially Christian, or unconditional, morality), life must continually and inevitably be in the wrong, because life is something essentially amoral -- and eventually, crushed by the weight of contempt and the eternal No, life must then be felt to be unworthy of desire and altogether worthless...."

"Bad! Bad! Can it be? Isn't he going - back? But you understand him badly when you complain. He is going back like anyone who wants to attempt a big jump." Friedrich Nietzsche

Friedrich Nietzsche Human all to human

"All religions bear the traces during the intellectual immaturity of the human race before it had learned the obligations to speak the truth. Not one of them makes it the duty of its god to be truthful and understandable in his communications." Friedrich Nietzsche

From Friedrich Nietzsche's book, Thus Spoke Zarathustra:
.
"You should first of all learn the art of earthly comfort,
you should learn to laugh, my young friends, if you are at
all determined to remain pessimists: if so, you perhaps,
as laughing ones, eventually send all metaphysical
comfortism to the devil and metaphysics first of all!
Or, to say it in the language of that Dionysian ogre,
called Zarathustra :

"Lift up your hearts, my brethren, high, higher!
And do not forget your legs! Lift up also your legs, you
good dancers and better so if you stand on your
heads!

"Anyone who fights with monsters should make sure that he does not in the process become a monster himself. And when you look for a long time into an abyss, the abyss also looks into you." Friedrich Nietzsche

Where the tree of knowledge stands is always paradise. That is what the oldest and the most recent serpents declare. Fredrich Nietzsche

"What is done out of love always happens beyond good and evil." Fredrich Nietzsche

"A casual stroll through the lunatic asylum shows that faith does not prove anything." Friedrich Nietzsche

"I cannot believe in a God who wants to be praised all the time." Friedrich Nietzsche

“I assess the power of a will by how much resistance, pain, torture it endures and knows how to turn to its advantage” - Friedrich Nietzsche

"I would believe only in a God that knows how to dance." Friedrich Nietzsche

"This crown of the laughter, this rose-wreath crown
I myself have put on this crown; I myself have
pronounced holy my laughter. No one else have I found
today strong enough for this.

"Zarathustra the dancer, Zarathustra the light one,
who beckons with his wings, one ready for flight,
beckoning unto all birds, ready and heady, a bliss
fully light-spirited one:

"Zarathustra the soothsayer, Zarathustra the sooth-
laughter, not impatient, not absolute, one who
loves leaps and side-leaps : I myself have put on this
crown!

"This crown of the laughter, this rose-wreath crown
to you my brethren do I cast this crown! Laughter
have I pronounced holy: you higher men, learn,
to laugh!"

The surest way to corrupt a youth is to instruct him to hold in higher esteem those who think alike than those who think differently. Friedrich Nietzsche

"The Christian resolution to find the world ugly and bad has made the world ugly and bad." Friedrich Nietzsche

"There are people who want to make men's lives more difficult for no other reason than the chance it provides them afterwards to offer their prescription for alleviating life; their christianity, for instance." Friedrich Nietzsche

"Whoever despises himself respects himself as one who despises." Friedrich Nietzsche

Thomas Henry Huxley actually summed up a lot of Nietzsche's ideas with "I do not say think as I think, but think in my way. Fear no shadows, least of all in that great spectre of personal unhappiness which binds half the world to orthodoxy."

On the negative side . . . . . Nietzsche's attitude toward women was quite negative.
I think that he could have made some of the things that he said clearer, for a wider audience, but that is really pushing it.

It is my belief also that his greatest mistake was his social isolationism.

Nietzsche, for the better part of his life, did not seem to have empathy. It was only right before his mental breakdown that he really showed some compassion . . . . it was at that point where, for the first time, I think that he may have realized his mistake, but I could just as easily be wrong . . . . I would like to think so, but you know how that is.

Have a book of his, but haven’t really got into it yet. May try again once I’ve finished The Art of Power by Thich Nhat Hanh.
