A book of images. A singular journey to/from the abstraction. "All these images act and react upon each others in all their elementary parts according to constant laws of nature. (...) I name matter all theses images and I name perception of matter these same images referred to the possible action of one determined image among them, my body." Thus Bergson introduces the immanence of the light relatively to the body receiving it, in the first pages of "Matter and Memory". Does this mean that Fernando suggests here some luminous fragments of the plane of immanence or the dark revelations of one of his planes of composition ? So emphasized the question seems to be lost between dazzle and blindness. Nevertheless, let's try to respond with discernment . . 'pictosophizing !" Prologue by Jef Safi with french, english, spanish and catalan versions.
