Black and Third World people are expected to educate white people as to our humanity. Women are expected to educate men. Lesbians and gay men are expected to educate the heterosexual world. The oppressors maintain their position and evade their responsibility for their own actions. There is a constant drain of energy which might be better used in redefining ourselves and devising realistic scenarios for altering the present and constructing the future.

For all the opportunities that arise from the Fourth Industrial Revolution - and there are many - it does not come without risks. Perhaps one of the greatest is that the changes will exacerbate inequalities. And as we all know, a more unequal world is a less stable one.

That night I lie out under the stars again. The Pleiades are there winking at me. I am no longer on my way from one place to another. I have changed lives. My life now is as black and white as night and day; a life of fierce struggle under the sun, and peaceful reflection under the night sky. I feel as though I am floating on a raft far, far away from any world I ever knew.

Changes... can only be effected by alterations in the original. The only thing not prerecorded in a prerecorded universe are the prerecordings themselves. The copies can only repeat themselves word for word. A virus is a copy. You can pretty it up, cut it up, scramble it - it will reassemble in the same form.

We must not, in trying to think about how we can make a big difference, ignore the small daily differences we can make which, over time, add up to big differences that we often cannot foresee.

The people are learning that you cannot leave decisions only to leaders. Local groups have to create the political will for change, rather than waiting for others to do things for them. That is where positive, and sustainable, change begins.
