There was a weird plastic cyborg whose CPU finally gave out last week who had a song whose chorus declared: "If you want to make the world a better place, take a look at yourself and make that change". I always considered that a repulsive sentiment - the height of smug middle-class Beautiful Soul-ism, the idea that all actual struggle to change the planet was worth less than some clown Visualising World Peace while pushing buttons at their middle-management position.
The opposite to this contention would be the idea that one's personality is irrelevant to The Struggle to bring something better into actual concrete existence. Tony Cliff said that "you don't need a beautiful chisel to carve Michaelangelo's David" - that is, if you make yourself the instrument of a great struggle, it really doesn't matter what kind of an unpleasant person you are. Robert Fripp would heartily agree, making it clear that everything good he's ever done musically came despite his personality, rather than because of it.
However, the essential question in that case is: what current are you actually tapped into? To put it another way - what quality is manifested in your actions - all of them? Are they actually "Building It Now", bringing the spirit of a better way into conscious existence with every conscious act you perform? Or are things going wrong despite your best intentions? Truly, as I think another commenter here noted, there isn't just one Higher Reality / Source of Popular Energy / Magickal Current / Class Interest - to put it another way, I think Robert Fripp is wrong to say that any act based on principle makes the world a better place. (What if that principle is "no negros?")
There was a Jewish carpenter who said something like "by their fruits shall ye know them". Chaos Marxism would agree that it really doesn't matter whether an organisation or current's propaganda or theory sounds good. What kind of practical activity does that current manifest? What does it bring into reality? What do we do when - and I have sad practical experience of this - you see a group of people who you agree with 100% on paper, bringing about destruction and division by what they actually do in the struggle?
Such a contradiction is surely the result of a massive "blind spot". A blind spot is an area of activity, which your conscious mind is determined to be unaware of, which is actually tapped into some kind of negative current. People with a big enough blind spot will be aware that everything they're touching turns to shit, but have no clue why. Probably, we end up blaming some horrible people who are obviously trying to destroy us out of sheer meanness. Hmmm.
So, in that sense, the Greater and Lesser Works have to go together. Our political and cultural activism - our attempts to bring something from a better reality into the Real World of Horrible Jobs - has to be combined with enough introspection to make sure that we're not just automatically dragging up something horrible from the Qlippothic realms, just because we never checked ourselves closely enough to see where all our psychic/energy connections are leading.
So - if you want to make the world a better place, best to take a look at yourself/ves if you find that what you're creating in the world is actually contrary to your conscious intention. It is in this sense that the personal is political - i.e. personal change must go together with political activity (or some kind of outwards focussed activity, artistic, cultural, social, whatever), otherwise the two spheres will foul each other up.
