for no other reason

I was having a day of What's The Point?

What's the point of howling against the monster of empire? Of challenging people around me about their ignorance? Of speaking, writing, raging, hoping?

I picked up a book at random, from a box of old books that my friend was taking to donate to the library. I opened it and read:

Each of us must speak our truth to power and work for a freer and more equitable world, if for no other reason than to sustain qualities in our own hearts and spirits that would be destroyed by inaction and apathy.

From Prayers for a Thousand Years, ed. Roberts and Amidon

That makes sense to me. To speak and act, not because I know it will change things, but because it keeps me human. It's something I know, something I've said myself, but I keep forgetting.
