Foucault tries to demonstrate how the great task
proposed by critic is to be in alert before the truth
speeches throughout our diverse and multiple
moral practices. We must focus on a history of
the present time, a history that dissolves the great
idealizations and, with its pass through concepts,
proposes a decomposition of the facts that lie
behind them. This means that the pillars supporting
the traditional history (systematicity, continuity and
consensus) would be affected now by a suspicion
on the speech of truth that supports this fact. In
other words Foucault, adopting the genealogical
view of Nietzsche, proposes to focus on the forms
of power that can be seen in every fact, emerge
from every moral practice and carry the fate of the
randomness and of the contingent.
