If you commit an act someone might dislike, they may not ever find out (if you don't ask for permission first). If they do, their forgiveness might not hold much weight if for example they were unreasonable in their original expectations, i.e. a catholic son uses contraception with his girlfriend.
Yes, it is easier to act without permission and then ask for forgiveness for doing so than to get permission to act in the first place. Once people have taken action, they can then simply say that they are sorry. If they instead ask for permission first, they are often told no and are thus less likely to ask for it.
Yes, this saying has been around for a while and it does prove true in many instances. Getting permission to do something can take days, weeks, or months, depending on the situation. But if the job needs to get done, it's often easier to just do it and ask for forgiveness afterwards. At least the job gets done!
The old adage, attributed to U.S. Naval officer Grace Hopper, that "it's easier to ask for forgiveness than to get permission" is not true. People can give permission for anything, but we all tend to hold onto grudges for a lot longer. This means that we don't hand out or receive forgiveness as often as we may like.
No, it is not true that "It's easier to ask for forgiveness than to get permission." When you ask for forgiveness, you have done or said something wrong, and by asking for forgiveness, you are basically telling that person that you were wrong. This is something that is hard to do for many people. However, it is easier to get permission for something.
