To put it simply, spoonism is an idea of a better society. Life in Valhalla sucks, so people search for someplace where they will be treated like people.
Since this game infected me with a healthy dose of passion (or an unhealthy dose of autism), in one of my playthroughs, I wrote down the truth of the spoonism. Let me share them with you.
'Never be full with the first spoon'. In spoonism, first spoon is an intention, second spoon is the result. Don't be satisfied with intention, aim for the result. When spoonist refer to people as 'first spoon', they mean the group that created the opportunity for them to gather. The second spoon are those people who will reach 'land of feast' (build korean communism).
'Your spoon may be different from mine, but we share the same bowl'. It is a beautiful way to say 'respectfully disagree'.
'Don't seek truths hidden behind masks'. Your past doesn't matter, we will treat you like a brother if you will help our cause.
'Only the hungry one can eat'. If you have a desire to do something, you will do it. Without a desire, you will do nothing.
'Those who lose their turf will suffer for as long as they live'. If you betray your ideals, you will suffer.
'Those who undergo hard times with you are your brothers'. brothers? comrades? Communism!!!
'When 10 people each give up a spoon full of their bowl of rice, they can make a new bowl of rice'. Communal property. Communism!!!
When you play this game long enough, not only spoonism stops being retarded, you start to understand spoonism as an idea and you start to understand what spoonists say. And sometimes they have a point.
