This foolish idea of shooting at the moon is an example of the absurd length to which vicious specialisation will carry scientists working in thought-tight compartments .... For a projectile entirely to escape the gravitation of the Earth, it needs a velocity of 7 miles a second. The thermal energy of a gramme at this speed is 15180 calories .... The energy of our most violent explosive - nitroglycerine - is less than 1500 calories per grammer. Consequently, even had the explosive nothing to carry, it has only one tenth of the energy to escape the Earth ... hence the proposition appears to be basically unsound.

THE thousand injuries of Fortunato I had borne as I best could, but when he ventured upon insult I vowed revenge. You, who so well know the nature of my soul, will not suppose, however, that gave utterance to a threat. At length I would be avenged; this was a point definitely, settled --but the very definitiveness with which it was resolved precluded the idea of risk. I must not only punish but punish with impunity. A wrong is unredressed when retribution overtakes its redresser. It is equally unredressed when the avenger fails to make himself felt as such to him who has done the wrong.
Edgar Allan Poe
If you seek reality you must set yourself free of all backgrounds, of all cultures, of all patterns of thinking and feeling. Even the idea of being man or woman, or even human should be discarded. The ocean of life contains all, not only humans. So, first of all abandon all self-identification, stop thinking of yourself as such-and-such or so-and-so, this or that. Abandon all self-concern, worry not about your welfare, material or spiritual, abandon every desire, gross or subtle, stop thinking of achievement of any kind. You are complete here and now, you need absolutely nothing.
Nisargadatta Maharaj
And it came to me then. That we were wonderful traveling companions but in the end no more than lonely lumps of metal in their own separate orbits. From far off they look like beautiful shooting stars, but in reality they're nothing more than prisons, where each of us is locked up alone, going nowhere. When the orbits of these two satellites of ours happened to cross paths, we could be together. Maybe even open our hearts to each other. But that was only for the briefest moment. In the next instant we'd be in absolute solitude. Until we burned up and became nothing.
Haruki Murakami
The Western approach to reality is mostly through theory, and theory begins by denying reality - to talk about reality, to go around reality, to catch anything that attracts our sense-intellect and abstract it away from reality itself. Thus philosophy begins by saying that the outside world is not a basic fact, that its existence can be doubted and that every proposition in which the reality of the outside world is affirmed is not an evident proposition but one that needs to be divided, dissected and analyzed. It is to stand consciously aside and try to square a circle.
Bruce Lee
If children had teachers for judgment and eloquence as they have for languages, if their memory was exercised less than their energy or their natural genius, if instead of deadening their vivacity of mind we tried to elevate the free scope and impulses of their souls, what might not result from a fine disposition? As it is, we forget that courage, or love of truth and glory are the virtues that matter most in youth; and our one endeavor is to subdue our children's spirits, in order to teach them that dependence and suppleness are the first laws of success in life.
Luc de Clapiers, Marquis de Vauvenargues
