Protagonism is a religion with no god, no holy books, no clergy or leaders, no prayers or rituals, nothing like that - only a moral system and philosophical tenets. Protagonism is a religion for the restless. Many people ask what the meaning of life is, and Protagonism first and foremost provides an answer. It requires a bit of philosophy.
There are four prime positive feelings that can be experienced by souls: pleasure, happiness, fun, and what I call 'Fuiki' (pronounced like 'figh
t + key' - I had to invent a name for it because I've never seen a natural language with one). Fuiki is the feeling you get when you do good. So, all people
spend their lives pursuing these four feelings with different priorities. The ones who pursue primarily Fuiki are called moralists.
Now you might object that if you're only doing a good act to feel good about yourself then it's just selfish and not really a good act. Fuiki is defined as the feeling you get when you do the right thing. But if it's only a good act if you're not doing it
for the Fuiki, then not every good act gives you Fuiki - a contradiction. This leaves us with only two options: either it still counts as virtuous if you're only doing it for Fuiki, or it's not possible to do a good act purely for Fuiki. I don't think anyone would argue for that.
Protagonists are simply the subset of moralists who also understand certain philosophical truths (detailed in the rest of the articles on the religion), and our purpose is to always do whatever exhibits the most virtue.
This does not mean I claim to be anything close to a perfect follower of my purpose, so please don't try to use my hypocrisy to dismiss what I'm saying.
So there's the centerpiece of Protagonism. Once you read the list of virtues, you will understand all that is essential.
