MICHEL FOUCAULT, info.

Dear all,
I am researching education for children and youth with learning  
difficulty/intellectual disability. I find the concept of pastoral  
power  very useful in understanding the ways in which an  
intellectually disabled is constructed as a problem for the education  
system. I would be grateful for guidance as to good discussions of  
pastoral power, both in Foucault himself and critical commentary.
Thanks
Judy
