Foucault did not adhere to the premise that a critique needs to be followed by a solution. In our daily conversations it is very common to expect a solution after an expressed critique, sometimes people demand it.
Foucault argued that the intellectual should never propose a solution, for this will imbalance his thought process. Proposing a solution will create an emotional attachment between the intellectual and the solution.
Through reasoning and research the intellectual should expose the gaps and defects in systems. The policy makers or managers should construct a solution from the critique.
It may benefit our daily conversations to adopt the same reasoning Foucault used.
