By denying to vegetal life the core values of autonomy, individualization, self-identity, originality, and essentiality, traditional philosophy not only marginalizes plants but, inadvertently, confers on them a crucial role in the current transvaluation of metaphysical value systems. From the position of absolute exteriority and heteronomy, vegetation accomplishes a living reversal of metaphysical values and points toward the collapse of hierarchical dualisms.
