[The passage you referred to is on page 169, Penguin edition].
How does this passage relate to the following famous passage from the 
"Preface to the Second Edition" (Penguin, p. 97)?
------------
"In France and England the bourgeoisie had conquered political power. 
>From that time on, the class struggle took on more and more explicit and 
threatening forms, both in practice and in theory. It sounded the knell 
of scientific bourgeois economics. It was thenceforth no longer a 
question of whether this theorem or that was true, but whether it was 
useful to capital or harmful, expedient or inexpedient, in accordance 
with police regulations or contrary to them. In place of disinterested 
inquirers there stepped hired prize-fighters; in place of genuine 
scientific research, the bad conscience and evil intent of apologetics."

* Would you not agree that it is important to distinguish between 
  different schools of bourgeois economic thought in terms of "validity" 
  and "absurdity"?
* Would you not agree that the "prize-fighter" passage is even *more* 
  valid today for "mainstream" economic thought (e.g. marginalism, 
  monetarism)?  Are the categories of those schools of economic thought 
  "socially valid, and therefore objective, for this historically 
  determined mode of production"?
* What implications does the above have for how we examine and critique 
  contemporary economic thought?
