"He who is hated by the people, as the wolf by the dogs - is the free spirit, the enemy of fetters, the non-adorer, the dweller in the woods."
— Friedrich Nietzsche

"Humanity has learned to call pity a virtue, when in the entire superior moral system it is considered a weakness."
— Nietzsche

“Kierkegaard and Nietzsche are among those who bring to philosophy new means of expression. Their objection to Hegel is that he does not go beyond false movement — the abstract logical movement of 'mediation'. They want to put metaphysics in motion, in action.”
— Deleuze

"Physiologists should bethink themselves before putting down the instinct of self-preservation as the cardinal instinct of an organic being. A living thing seeks above all to discharge its strength: 'self-preservation' is only one of the results thereof. — Let us beware of superfluous teleological principles! — one of which is the whole concept of 'self-preservation.'"
— Nietzsche, Will to Power

"The feeling of being surcharged, the feeling accompanying an increase in strength, quite apart from the utility of the struggle, is the actual progress: from these feelings the will to war is first derived."
— Nietzsche

"Pleasure appears with the feeling of power.
Happiness means that power and triumph have entered into our consciousness.
Progress is the strengthening of the type, the ability to exercise great will-power: everything else is a misunderstanding and a danger."
— Nietzsche

“Difficult tasks are a privilege to the Overmen; to play with burdens that crush others, a recreation. Knowledge—a form of asceticism. They are the most honorable kind of man: that does not preclude their being the most cheerful and the kindliest.”
— Nietzsche

"A rich and powerful soul not only gets over painful and even terrible losses, deprivations, robberies, and insults: it actually leaves such dark infernos in possession of still greater plenitude and power."
— Nietzsche

Nietzschean Socialism — Left and Right, 1890-1933 by Steven E. Aschheim
It was not surprising that when the radical right sought to appropriate the idea of socialism for its own purposes Nietzsche was the central inspiration in such a transition.

The right now offered a ‘national socialism’ as a counterweight to the Marxist idea of international proletarian revolution. Its ideologues could proclaim themselves socialists not only because they assigned to the state authoritarian powers to regulate socio-economic life along quasi-corporate lines, but also because they couched their analyses of society in terms of a biting critique of the bourgeoisie and accorded to the lower classes a major role in their visions of a post-liberal, post-Marxist, national regeneration. Nietzsche provided a fruitful source for these themes. This was a conception which conflated the national with the social. Dedication to the nation would create a socialism of the volksgemeinschaft, a viable substitute for the socialism of class.
