The Change for Revolution

Despite the all the ideologies or “Methods” of Detournement that Debord gives us, I became interested within the first few paragraphs. In an overt way we are given a charge to understand what we are capable of doing. How do we change the past for our future, is it by the way of propaganda and “Detournement” of which Debord speaks of?
It is possible to see the relevance of this today within our visual culture and how the context can be altered for something new. Debord writes, “It goes without saying that one is not limited to the correcting a work or to integrating diverse fragments of out-of-date works into a new one… “Art and the visual language has seen this before the understanding of Detournement was coined, and as well after. Artists like Joel Peter Witkin, Hanso, and Goyaz are contemporaries that express this at their will. How are they making the change? And what depths will be taken to “alter” the true context of what we believe is real or truth? What would our society be like with out the creation of Adbusters. A corporate magazine geared to silence the corporate industries by using imagery of popular icons and logo marks. “Joe Chemo”, was an Advertisement against smoking that targeted R.J. Reynolds Tobacco and their “Camel” cigarettes. Hanso, a Swiss designer has created much work that uses the propaganda margin. After further articulation of a certain company, Hanso became aware that during WW2, money and support was given to the Nazi party. In their 2000, 100th year career posters, Hanso used past historic images and children to spell out the word Nazi. This was unaware to most unless seen in the whole context of each of the 4 posters.
…”one can also alter the meaning of those fragments in any appropriate way leaving the imbeciles to their slavish reference to “citations.” After this said and more read, my question becomes, when do we stop the already re-creation? If everything is being re-done to re-invent context, does authorship exist and who can place their name amongst it?
I read that the French word detournement means deflection, diversion, rerouting, distortion, misuse, misappropriation, hijacking or otherwise turning something aside from its normal course or purpose. Debord makes it possible for us to see ways into reshaping and defining our world; I suppose the only question I leave with is how do we continue to do this?
