"<p></p> <p>In times like ours, when everything happens not only horizontally but also vertically, one does the right thing if one learns to act with the caution of a front-line soldier. For to be clever, not petty, but calculating in one's movements, to be concerned with space, situation, danger, to act in the direction of least resistance, to be untimely in one's attack, but courageous and calm at the moment of attack, is to be clear in courage. To be a soldier in battle is a dangerous task, but to be a citizen in an era of total, vertical assaults of life is no less dangerous. And we live in such an era. Let us therefore calculate our movements, day and night, at every possible opportunity, so that in the great struggle which has marked us out as warriors, we do not waste our strength in vain. Night and day we must fight. Our work, our entertainment, our reading, our concepts of life, our knowledge and experience, all these are weapons in this struggle. So let us take our place in the humble and dangerous cover, in the den of our lives, watching the enemy's every move, and not wasting our energies or ammunition prematurely. And meanwhile, if the sky is starry and the enemy is asleep, let us look at the stars.</p>"
