A line is a dot that went for a walk. - Paul Klee

Looking back at the end of the year created a little more serious mood than before. To bring children [his son ] in the world is no trifling matter! Over the entire horizon, bluish, phosphorescent flashes of sheet shining.. ..In fact, I really do go out into the snow [near Munich] in all seriousness, station myself there, freeze, freeze stiff, but work. I accomplish little in comparison with the abundance around me, but I accomplish a great deal in comparison with the poverty and simplicity of a small bourgeois homestead.

The changeover was complete; in the summer of 1907 I devoted myself entirely to the appearance of nature and upon these studies built my black-and-white landscapes on glass, 1907/1908.

Thoughts at the open window of the payroll department [in a military barrack - World War I.]: That everything is transitory is merely a simile. Everything we see is a proposal, a possibility, an expedient. The real truth, to begin with, remains invisible beneath the surface. The colors that captivate us are not lighting, but light. The graphic universe consists of light and shadow. The diffused clarity of slightly overcast weather is richer in phenomena than a sunny day. A thin stratum of cloud just before the stars break through. It is difficult to catch and represent this, because the moment is so fleeting. It has to penetrate into our soul. The formal has to fuse with the Weltanschauung [world view].
