In a dispassionate comparison of the relative values of human and robotic spaceflight, the only surviving motivation for continuing human spaceflight is the ideology of adventure. But only a tiny number of Earth's six billion inhabitants are direct participants. For the rest of us, the adventure is vicarious and akin to that of watching a science fiction movie. At the end of the day, I ask myself whether the huge national commitment of technical talent to human spaceflight and the ever-present potential for the loss of precious human life are really justifiable.
Youth is not a time of life - it is a state of mind. It is not a matter of red cheeks, red lips and supple knees. It is a temper of the will; a quality of the imagination; a vigor of the emotions; it is a freshness of the deep springs of life. Youth means a tempermental predominance of courage over timidity, of the appetite for adventure over a life of ease. This often exists in a man of fifty, more than in a boy of twenty. Nobody grows old by merely living a number of years; people grow old by deserting their ideals.
The usual hero adventure begins with someone from whom something has been taken, or who feels there is something lacking in the normal experience available or permitted to the members of society.

I do not see any reason why animals should be slaughtered to serve as human diet when there are so many substitutes. After all, man can live without meat. It is only some carnivorous animals that have to subsist on flesh. Killing animals for sport, for pleasure, for adventures, and for hides and furs is a phenomenon which is at once disgusting and distressing. There is no justification in indulging in such acts of brutality. . . Life is as dear to a mute creature as it is to a man. Just as one wants happiness and fears pain, just as one wants to live and not to die, so do other creatures.
I speak and speak,” Marco says, “but the listener retains only the words he is expecting. The description of the world to which you lend a benevolent ear is one thing; the description that will go the rounds of the groups of stevedores and gondoliers on the street outside my house the day of my return is another; and yet another, that which I might dictate late in life, if I were taken prisoner by Genoese pirates and put in irons in the same cell with a writer of adventure stories. It is not the voice that commands the story: it is the ear.
