I was contemplating a bit on two separate (though related) matters:
1. responsibility: ie. responding to society as we are able
2. power: that every individual has an impact. even those not considered 'powerful' impact those around them in all kinds of large and small ways, hence we all have far more power than we may have imagined.
The two can overlap, and you've already gotten into the overlapping in your post above. I think that recognizing our power makes us more responsive, more able, thus more responsible.
Never linger too long with the ignorant,
throw stones at their talk.
Walk only with the lovers,
the mirror of the soul gets rusty when
dipped in muddy water.
