[Xmca-l] Re: Resending LSV/ANL on crisis in ontogengy

[Andy Blunden]

I think Huw put the alternative interpretation of Leontyev's words very 
well. There *is* a difference there, but it is not as profound as at 
first sight.
I don't agree with the cast David has put on my view though. It is 
precisely in understanding the crises as being transitions between SSDs 
which is where SSD is invaluable as the unit.
In general of course it is true, that a unit shed light on a specific 
problem, and is not the key to everything.
