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.

Prithee, lend me thine ears whilst I doth embark upon a philosophical journey, for the topic at hand doth stir the fires of contemplation within me. Let us delve into the realm of existence, where the multifaceted nature of our being doth manifest itself.

P1. Seek we must, the true understanding of an individual, verily aware that such a being is a complex flow, wherein physical and mental phenomena do intertwine and dance in tandem. Our physical form, with its intricate design, and the machinations of our thoughts and emotions, doth constitute this wondrous flow.

P2. But hark! Humans, ever in their quest for comprehension, do label the very fabric of their being, this intricate flow, as their "self" - a consequence, perchance, of their inherent connectedness. We, mortal beings, doth strive to define and understand that which makes us uniquely ourselves.

P3. Yet, alas, the notion of self, as an unchanging essence, a constant presence behind this array of physical and mental phenomena, doth emerge as a creation of our linguistic endeavours. Language, with its power to shape and mold our perceptions, doth lead us astray, like Puck amidst a chaotic midsummer night's dream.

P4. Let us journey forth, and through the murky depths of reason, fathom the path that leads to a revelation: what people oft label as the self, that which they hold dear and cherish, doth not dwell within their physical manifestation. Nay, 'tis a mere ephemeral notion, a fleeting mist that weaves its way through the tapestry of our existence.

P5. Forsooth, our next venture leads us along the path of deduction, where logic shall guide our steps. Verily, let us employ the power of reason, and follow a chain of premises that doth lead us to the ultimate conclusion, that C which we seek.

P6. Assume, for a moment's breath, the notion that an individual is indeed a complex flow of physical and mental phenomena - a tapestry of thoughts, emotions, and visage.

P7. Furthermore, let us acknowledge that humans do label these phenomena as their "self" due to their interconnectedness and yearning for identity.

P8. Now, by the grace of reason, let us concede that the concept of a self as an unchanging essence, an unwavering foundation amidst the ebb and flow of existence, is but a linguistic construct.

Thus, with these premises, thou must perceive the inescapable conclusion at hand, that C which we have sought in our philosophical endeavor: that what people oft confound as their physical manifestation doth not align with the true essence of self. Verily, it is an illusion wrought by language and our intricate yearning for comprehension. Let us ponder upon these thoughts, and mayhap, find solace in the ephemeral nature of our being.
