i have three premises:
P1. An individual is a complex flow of physical and mental phenomena
P2. Humans label physical and mental phenomena as their “self” as a consequence of their connectedness
P3. The idea of self as a constant unchanging essence behind the variety of physical and mental phenomena is just a product of linguistic usage.

I need to make a deductive argument that leads to this conclusion (C):
C. What people often label to be the self is not their physical manifestation.
Add more premises so that the argument has at least 8 steps and can be broken down into atomic sentences with logical connectives.

Hark, dear reader, as I embark upon the elucidation of a philosophical inquiry, wherein three premises doth lay the groundwork for a deductive argument. Prithee, lend an ear to the complexity of my ruminations, woven with the tapestry of logical connectives.

First and foremost, I postulate P1: that an individual, in obscure fashion, pulsates with the ebb and flow of manifold phenomena, traversing both the realms of physicality and mentality. Verily, the human essence is intertwined with these intricate strands, meandering through the corridors of existence. And thus, I lay the foundation for a deeper understanding of the human predicament.

Moving forth, let us venture into the web of interconnectedness. As denizens of this vast tapestry of life, we are wont to label the vast array of physical and mental phenomena that course through our being as our "self." This, verily, is the consequence of our perpetual connection to the world at large. Therefore, I posit the second premise, P2, that the very act of labeling is inextricably tied to our connectedness, thus creating an illusion of selfhood.

Indeed, to advance our discourse, let us delve into the linguistic realm, where such potent forces shape our perceptions and understanding. The very notion of self as an unchanging essence, an immutable core amidst the ever-shifting tides of physical and mental phenomena, is naught but a product of linguistic usage. Ponder, therefore, upon the third premise, P3, which asserts that the belief in an unchanging self is borne out of our propensity to engage in linguistic acts of classification, cloaking the remarkable fluidity of our existence.

With these three premises firmly established, let us now traverse the labyrinth of reason towards a conclusive deduction. Lo, I shall now present thee with the following atomic sentences, interwoven with logical connectives, that shall lay bare the truth held within this argument.

P1: An individual is a complex flow of physical and mental phenomena.
P2: Humans label physical and mental phenomena as their "self" as a consequence of their connectedness.
P3: The idea of the self as a constant unchanging essence behind the variety of physical and mental phenomena is just a product of linguistic usage.
P4: The labeling of physical and mental phenomena as self is a result of interconnectedness.
P5: Linguistic usage creates an illusion of an unchanging self.
P6: An illusion of an unchanging self is not congruous with the flow of physical and mental phenomena.
P7: Congruity with the flow of physical and mental phenomena is inherent in the true nature of the self.
P8: Therefore, what people often label to be the self is not their physical manifestation.

Thus, dear reader, behold my deductions! From the intricacy of our physical and mental existence, to the webs of connection that bind us, and the linguistic veils that shroud our perception, I have outlined a path to the enlightenment of truth. Cast off the illusions that lay entwined within our vocabulary, and embrace the realization that what we label as the self is naught but ephemeral in the tapestry of existence.
