Mankind desires to love and be loved.
People yearn for acceptance and to be included.
One way people sense inclusion and acceptance is in reflecting people and things they admire.
The most obvious sign is by appearance; clothing, mannerisms, speech, attitude.
It shouldn't be surprising then when women layer on makeup in attempting to reflect some ideal of beauty.
Same goes for the man who surrounds himself with expensive things to bring value to himself.
For a woman who is already accustomed to having the makeup, to go a day without anything put on her face would be quite difficult.
Same for a man to take public transportation who is used to traveling in his expensive car, or to patronize the dollar menu at a fast-food eatery when he is used to filet mignon and caviar.
The external things, although serving a purpose in themselves, are usually absorbed into the psyche to support and supplant a concept of value
Yet the values in society can be vacant of the order society's building blocks have been built upon.
We all have a taste of vanity.
Even the most hardened religious zealot is replete with vain aspirations regarding the manner they religiously carry themselves around other zealots.
Certain sects of Islam vainly argue over how many times a 'true' believer is to pray throughout a regular day; their justifiable external evidences somehow implying an internal righteousness and bringing a sense of God's acceptance of their efforts.
Certain sects of Christianity argue over a plethora of issues having little to do with love for one another and being gracious and understanding of others; their vain quibbling over words somehow marking others as unrighteous or unsaved, making themselves feel secure and saved.
The philosophy of those too afraid or too uninformed to acknowledge a God may agree with other philosophies; adopting a vain religious rhetoric denying evident eternal attributes, reflecting the conceit they may point out in believers.
Sadly we see the world in default worship of itself, of things made by man's hands - from the money used to buy and sell things, to the imagery of others unconsciously imitated by so many... all in attempts to find that love and acceptance that every human being cannot deny they want, but are confused as to how to realize it.
