How to Act In Modern (Polite) Society

Without meaning to add any religious bias, I am a self-confessed sinner. Some may not believe in the idea of sin so for them I'll call myself a 'wrong-doer'. Certain things have come to light in the past few days that have made me evaluate my own past and current behaviour whilst also looking at accepted modes of behaviour in society. Is one to take the prevailing approach, that borders on hedonism and nihilism; a lifestyle of 'camp' reverie that screams 'who cares'? Or is it possible to take a stiff line and adopt an antithetical viewpoint on modern society. In other words, can one maintain a standpoint of high-seriousness and sincerity, displaying concern for the ills of the world in a virtuous manner? It would appear that both modes of thought ultimately only lead to two things-soul destruction or insanity! To continue to indulge in modern society's trough of self-absorbed moments of pleasure can bring misery and heartache when one ponders the fruitlessness and meaninglessness of it all. Though to strive to reconcile the problems that lie within society may result in rejection and madness, with yourself left baffled and confused as to why, despite the problems we face, the world is shouting you down as the party must go on. These of course are undeveloped and simplistic musings as yet. I'm not trying to set myself up as a righteous polemicist. I am merely attempting to comprehend some of the questions that accompany the everyday. Perhaps though, I am just wasting web space. Certainly, modern society may come to this conclusion. After all, 'who cares'?
