Having gone through classical training in architecture, I've long owned Paul Klee's Pedagogical Sketchbook, a relic of the German Bauhaus which defined so much of what is still taught today in architecture schools around the world. Sitting among my collection of textbooks and other recommended readings from school, Klee's slender treatise is the one book I was never able to dig into over the course of my university years, despite being by far the thinnest and many would say "fluffiest"of the lot.
After resolving to sit down and give the book a fair shot, with a (very) open mind, I've been pleasantly surprised at the insights I've been able to glean. Truth be told, the majority of the book still reads like a foreign language to me, a mess of lines with superimposed text sometimes so far divorced from the so-called "diagrams" neighbouring it that I glide through page after page completely lost. Every so often however, Klee will describe a simple idea or a concept in such great clarity and in such an original way that for a fleeting moment, the whole of the "sketchbook" makes sense to you. For those rare instances alone, this curious book is worth the time of any student of art, architecture, or philosophy.
