—- The turn of the 19th century Philosopher Friedrich Schelling was a contemporary critic of Emmanuel Kant, who was ostensibly the father of the philosophical mess we call modernity but particularly of the 20th century form of it.
It is possible we are emerging from that mess presently.

I say that mental health is the signal and symbol of this emergence for our time.
But Back to Schelling
Schelling was noted for making the comment that Kant’s proposals would lead to nihilism. And that’s exactly what we got for the past 200+ years.
Philosophy, being inseparable from the world itself, integral (less a proactive means to capitalistic identity profits) and active in the iteration of all things known to be real, presents mental issue the realization and pronunciation of the lived conceptual experience of nihilism, the various manifestations of the subject caught ungrounded in the real substance of the universe.
It is through the lens is filtered the discrepancy between the positive formative substance and the positive material nothingness, that is, as the basis from which subjective meaning is able to be understandable as such, as an existent Being, that the various psychological disorders to their various intervention qualities, approaches, and attitudes are informed.
Through this lens psychology is helped as it hobbles along its presumptuous path. For, in its current manifestation, it does not distinguish between what is physically disruptive, which is to say, what is an actual disorder, analogous as a broken knee prevents one from walking, From mental health issues, which is to say the basis through which, say, I understand myself in order to be a productive member of the operating universe, and working towards the life that I want. Where there might be a physical disfunction of the brain which prevents a kind of real ability for actualization of agency, there might psychology have footing. But beyond that, we merely find pronunciations of a nihilism that is unable to reconcile itself with the true facets of existence. And we find this iterated through the 20th century philosophies, in their different subjective ways, especially.
Philosophy begins upon the subject realizing its own limitation in knowing as a lived experience of knowing: this is effective agency. This rather than perpetually being caught up in its own subjectivity merely affirming its ability in the world, to make it of its own meaning. Philosophy begins, as Aristotle might have said, when we begin to notice and make semantic distinctions at proper junctions of actual universal truth. But these junctions cannot be noticed when the world is filled with only modern psychological subjects; the junctures are routinely sutured over to be intentionally missed.
So it is that the beginning of philosophy comes through the modern forms of mental health of or over psychology, rather than the strict philosophical tradition of the Judeo-Greek tradition of the “scientific” Western mind’s psychology defining of mental health – Not for another prescription, not another oppressing ideological subjective political form. Exactly through seeking mental health and authentic engagement with the truth of reality philosophy as a grounded intellectual, somatic, and cognitive exercise begins.
