In 1967 I began writing this book in New York as an analysis of what had been enunciated in the visual arts, conditioned between technology and rebellion. When I return to Buenos Aires I continued to write (until 1972) in a different context where rebellion had revolutionary cravings for the prevailing dictatorship. In the early 1970s, very tough times began in our country (Argentina) and in Latin America in general. For that reason, I didn't publish it. It is now unquestionable that what this work called "militant thinking of change" begins to develop again: the creative and answering act first and foremost in action. Its development in certain fields such as the feminist revolution, ecological awareness and the assessment of free sexual choice are manifestations of a cultural revolution. For this reason, publishing [this book] today makes sense again even if it was written half a century ago. The coordinator of the Centro Cultural de la Cooperación, Juan Pablo Pérez, wrote the appendix of the book and is the result of a series of reflections that occupied Luis Felipe Noé during his stay in New York and on his return to Argentina, between 1967 and 1972. The book was written in a period of estrangement from painting, overturned to intense writing at a time of crisis, which led Noé to another type of intellectual, political and theoretical production.
