"The only time a man needed a lot of women was when none of them were any good."

From "Women." 

"If something bad happens you drink in an attempt to forget; if something good happens you drink in order to celebrate; and if nothing happens you drink to make something happen."

Another gem from the novel, "Women." 

"I've got to get back to the typewriter, I thought. Art takes discipline. Any asshole can chase a skirt."

From the novel, "Women." 

"Human relationships didn't work anyhow. Only the first two weeks had any zing, then the participants lost their interest. Masks dropped away and real people began to appear: cranks, imbeciles, the demented, the vengeful, sadists, killers. Modern society had created its own kind and they feasted on each other. It was a duel to the death--in a cesspool. The most one could hope for in a human relationship, I decided, was two and one-half years."

From Women.

"yet there bad been warmth, it had not been without feeling, dead meat coupled with dead meat. I detested that type of swinging, the Los Angeles, Hollywood, Bel Air, Malibu, Laguna Beach kind of sex. Strangers when you meet, strangers when you part--a gymnasium of bodies namelessly masturbating each other. People with no morals often considered themselves more free, but mostly they lacked the ability to feel or to love. So they became swingers. The dead fucking the dead. There was no gamble or humor in their game--it was corpse fucking corpse. Morals were restrictive, but they were grounded on human experience down through the centuries. Some morals tended to keep people slaves in factories, in churches and true to the State. Other morals simply made good sense. It was like a garden filled with poisoned fruit and good fruit. You had to know which to pick and eat, which to leave alone." 

One of my personal favorites from Women.

"I was still naked. I looked down at my penis: you dirty son-of-a-bitch! Do you know all the heartache you cause with your dumb hunger?"

Another comedic gem from Women.

"And yet women--good women--frightened me because they eventually wanted your soul, and what was left of mine, I wanted to keep."

From Women [his third novel].
