If [Sean] doesn't see me a few days or if I'm really, really busy, and I just sort of get a glimpse of him, or if I'm feeling depressed without him even seeing me, he sort of picks up on it. And he starts getting that way. So I can no longer afford to have artistic depressions. If I start wallowing in a depression, he'll start coming down with stuff, so I'm sort of obligated to keep up. And sometimes I can't, because something will make me depressed and sure as hell he'll get a cold or trap his finger in a door or something, and so now I have sort of more reason to stay healthy or bright.

We went to America a few times and [Brian] Epstein always tried to waffle on at us about saying nothing about Vietnam. So there came a time when George [Harrison] and I said 'Listen, when they ask next time, we're going to say we don't like that war and we think they should get right out.' That's what we did.

I don't believe in Beatles, I just believe in me.

I can't remember anything without a sadness so deep that it hardly becomes known to me, so deep that its tears leave me a spectator of my own stupidity.

Our society is run by insane people for insane objectives. I think we're being run by maniacs for maniacal ends and I think I'm liable to be put away as insane for expressing that. That's what's insane about it.

I believe that as soon as people want peace in the world they can have it. The trouble is they are not aware they can get it.

I used to be cruel to my woman, and physically - any woman. I was a hitter. I couldn't express myself and I hit. I fought men and I hit women. That is why I am always on about peace, you see. It is the most violent people who go for love and peace. Everything's the opposite. But I sincerely believe in love and peace. I am a violent man who has learned not to be violent and regrets his violence. I will have to be a lot older before I can face in public how I treated women as a youngster.
