The simple and sweet answer: now.
The only problem with that answer, no matter how true it may be, is it is a powerful example of the truth behind the phrase ‘easier said than done’. In theory, it could be the most wonderful thing ever to happen to you, but in practice, there will always be some evident risk undermining the whole experience. In theory, an action could have the potential to save the world, yet in practice, the ultimate decision maker will always have calculated their potential reward, regardless of whether said thought influenced their ultimate decision. Being in the right sometimes means having to accept a compromise, delaying your own wanted action in the name of appeasing another.
Yet regardless of the above, do people truly want to live in a society where individuals are free to do as they want, recklessly acting on impulses alone? One person’s right is another person’s sin after all. People are not infallible. It is only through stopping, through thinking, through calculating, that we make ourselves less subject to such wrongs. Isn’t that the right thing to do ultimately?
