Hmmmm. The Ethos of Consumerism and Luxury Consumption.
Whence the battle?
It isn't complicated, only confusing to one who is double minded [simultaneously holding ethos from two competing sources of truth] or has no absolute source of truth.
One's ethos or values are a direct product of one's world view.
One's world view is merely a product of one's truth source or source of truth. Whatever one chooses as a truth source, it then becomes the foundation of the worldview used to assemble the ethos or collection of truths or values used to establish one's internal ethics or rules of conduct whether the conduct or activity is consumerism or luxury consumption.
Most Eastern philosophies promote the idea that truth is found within, yet acknowledge that all internal truth first existed outside of what was an empty vessel at birth.A small subset believe that truth is found after one returns to the state of an empty vessel.
In first case, all truth is relative to the individual since the individual chooses what is truth using the worldview they possessed at birth or nothing. typically truth for these individuals is anything that gives them pleasure or makes them feel good. In the second case, truth is found at the bottom of a vessel emptied of its ethos or nothing. So much for the State of Nirvana. For both of these Eastern philosophical systems the end game is the same; truth is ultimately based on nothing or no-thing.
Most Western non-monotheistic philosophies promote the idea that truth is relative to the individual and that there is no absolute truth. This is classic existentialism. where the individual is their own truth source. Sound familiar? A humanistic expression of this would be; "If it feels good [to you], do it". Another class of Western philosophical thinking holds that everything is a product of random events or that everything came ultimately from no-thing; e.g., Nietzsche's statement; "God is dead."
Without an external absolute truth source, both Eastern and Western philosophical traditions find that truth comes from the one of two primary sources: one's self or no-thing.
Since all philosophies that holding that the individual is their own source truth typically believe that everything came from no-thing, all above described systems have the same truth source: no-thing. Many philosophers from these schools of thought claim to hold the scientific method in high esteem despite the fact that they are promoting, in the most double minded manner possible, a philosophy counter to at least once one Scientific law that has proven to be true absolutely within the space-time continuum; e.g., "Some-thing cannot come from no-thing."
Truth is a thing and a true idea with material reality. How could it come from no-thing?
If no-thing is the ultimate source of truth for one, then to them everything will be appear to be true at one time or another at any given place in the space-time continuum. After a lifetime of self deceit, this lot are usually more than disillusioned, "enjoying" a state of apathy or despair.
"The mass of men lead lives of quiet desperation. What is called resignation is confirmed desperation. From the desperate city you go into the desperate country, and have to console yourself with the bravery of minks and muskrats. A stereotyped but unconscious despair is concealed even under what are called the games and amusements of mankind. There is no play in them, for this comes after work. But it is a characteristic of wisdom not to do desperate things." -- Henry David Thoreau
Executive Summary:
Without an external truth source, every idea or thing must be taken to be true as everything has a relative truth or is true relative to something. And no one can deny another their truth source even if that truth source is nothing or no-thing.
Example: a unicorn is a true idea despite the fact that the idea is a merely chimera with no material reality of two pre-existing ideas but completely independent ideas, each both a relative and absolute truth by reason of their prior and current existence; a horse and a horn from an oryx. While the unicorn has never demonstrated a material existence, and hence some form of absolute truth in this space-time continuum, one cannot deny that the unicorn is a true idea or a truth relative to ones that believe unicorns are true bor real.
The only way to determine that a unicorn is a idea that is absolutely false or false from any particular or peculiar point of view in the space-time continuum because it is only a non-material chimera, one must have access to an absolute source of truth that is independent of space-time or eternal.
If one holds some external truth source to be truth absolute, such as a believer in a mono-theistic religion, while simultaneously holding values from a competing philosophical system such as humanism, existentialism, empiricism, skepticism, taoism, objectivism, gnosticism, etc., to be true, THEN, one will be double minded and simultaneously hold values originating from two incompatible truth sources.
When truth sources are incompatible, either one is true or both are false, but they cannot both be simultaneously true.
Holding no absolute truth source because you believe that none exist or believing what you want because it makes you feel good, will leave you powerless to argue with another about their truth without looking like or feeling like a fool. If you have no truth source, you should have no complaint about another's; the end.
If double minded, you likewise cannot deny another their truth until you resolve your competing truth sources to one that is absolutely true. You can have no complaint about another's truth source, since you have proven that competing truth sources are no obstacle to "truth" or ethos by your actions. In practice, you have no truth source and it would be foolish to deny another their's.
Executive Summary:
One can never successfully argue against any idea without first adopting some form of an absolute source of truth.
Unless you claim some form of absolute truth which denies the truth of Consumerism or Luxury Consumption, you must then accept both to be true even if it doesn't make you feel good. You cannot rely on an internal standard that is only true for you to deny another their truth. Likewise, if your truth source is nothing, then you must accept everything to be true and in this case ethos supporting both, since you have no basis for determining otherwise.
Before you can defeat a false ideology based upon an ethos relative to an individual or arising from no-thing, one must first find a absolute source of truth or a source external to one's self that is absolute or true both inside [and ultimately outside] the space-time continuum.
Consumer Warning:
If you ever find such an absolute source of truth, it may become quite difficult to argue with others whose ethos or values [hence, arguments and actions] are based on no-thing or just upon those that would give them pleasure or a feeling of happiness.
