I read this quote yesterday. For some reason, it haunts me.
If you've spent any time around horses, you know a stallion can be a major problem. They're strong, very strong, and they've got a mind of their own. Stallions typically don't like to be bridled, and they can get downright aggressive --- especially if there are mares around. A stallion is hard to tame. If you want a safer, quieter animal, there's an easy solution: castrate him. A gelding is much more compliant. You can lead him around by the nose; he'll do what he's told without putting up a fuss. There's only one problem: Geldings don't give life. They can't come through for you the way a stallion can. A stallion is dangerous all right, but if you want the life he offers, you have to have the danger too. They go together.
