The conditions were now perfect, it seemed to me, for thinking. A few minutes earlier, on the maritime platform, I had stopped to watch the rain fall in a bright projected beam, in the exact space delineated by the light, enclosed and yet as devoid of material borders as a quavering Rothko outline, and, imagining the rain falling at this place in the world, which, carried by gusts of wind, passed through my mind, moving from the shining cone of light to the neighboring darkness without it being possible to determine the tangible limits between the light and shadows, rain seemed to me to represent the course of thought, transfixed for a second in the light and disappearing the very next second to give way to itself. For what is the act of thinking—if it's not the act of thinking about something? It's the flow of thought that is so beautiful, yes, the flow, and its murmur that travels beyond the world’s clamor. Let yourself attempt to stop thought, to bring its contents to light, and you'd end up with (how could I say, how could I not say rather) trying to preserve the quavering, ungraspable outlines, you'd end up with nothing, water slipping through your fingers, a few graceless drops drying out in the light. It was night now in my mind, I was alone in the semi-darkness of the booth and I was thinking, protected from outer torments. The most favorable conditions for thinking, the moments when thought can let itself naturally follow its course, are precisely moments when, having temporarily given up fighting a seemingly inexhaustible reality, the tension begins to loosen little by little, all the tension accumulated in protecting yourself against the threat of injury—and I had my share of minor injuries—and that, alone in an enclosed space, alone and following the course of your thoughts in a state of growing relief, you move progressively from the struggle of living to the despair of being.
