Since December 2016 I’ve gone around asking the same question to everyone I’ve met:

How can there be goodness in the world, if everyone who donates to a beggar does it, either consciously or not, because they know that they’re doing good when it occurs? 

I get many answers, none of them bleak. 

“The fact that they do it as the least selfish course of action is something to think about.”
