I question the need for it and would say its just another form of mimicry we can do without.

There are a number of assumptions with most science fiction.

1) White people still run the galaxy
2) Science is a linear neat progression
3) That civilisation's actually progress in their thinking and do not become more barbaric.
4) That science can solve anything and everything.
5) The denial of spiritual realities.
6) More machines and 'artificial intellenge' equals progress and that there is no critical point to be reached when nature reduces man to limited technology thorugh force. ( Think global warming).

Would a story of human beings with pronounced spiritual powers/ through heightened training and a shift in the education of humans be African/ African Caribbean science fiction? Is science limited to the physical realm?

Just some of the things that it brings to mind.
