I have no doubt that we can create a really miraculous future. I am just increasingly pessimistic about our collective desire to do so.
So what if there’s a low collective will at the moment. Do your part to be part to grow the collective will to good. Go volunteer for a good cause (food bank, community organizations, etc.), donate to good causes, just be friendly to other people you see.
> Optimism is the precondition for doing good.
It is still possible to do good when things are bleak and there is no possible way out - just because doing good is the right thing[1]. Optimism helps a lot for morale, but is not a precondition.
1. e.g. the 2 people who were pictured comforting each other while trapped at the top of a burning wind turbine.
Optimism doesn't necessarily mean hope. It can mean belief in an afterlife. An end to a suffering. Or gratitude for having someone else in a terrible moment.
I think OP is correct. You can't have good without optimism. Your point, which is also correct, is you can do good without hope.
op·ti·mism (noun): hopefulness and confidence about the future or the successful outcome of something.
