Based on a dialogue between professors Simon and Argyris , in the third article by Dr.Saadat, the rntion1i and self — actualizing models of man as a basis for designing efficient organization are examined. Saadat asserts that while the conclusion is inescapable that a multitude of factors, including rationality and self—actualization, should be considered when designing an organization, there is considerable evidence supporting Simon’s argument that rationality, as embodied in formal organization, has made economic development and economic affluence possible. And this, in turn, has facilitated self actualization. This is a point worthy of notice in developing countries.
