Those who cannot remember the past are condemned to repeat it.

The world is so much bigger than we are. It contains things that we can't even imagine, and if we limit outselves to our own minds, we'll never grow.

How dull it is to pause, to make an end,
To rust unburnish'd, not to shine in use!
As tho' to breathe were life! Life piled on life
Were all too little, and of one to me
Little remains: but every hour is saved
From that eternal silence, something more,
A bringer of new things; and vile it were
For some three suns to store and hoard myself,
And this gray spirit yearning in desire
To follow knowledge like a sinking star,
Beyond the utmost bound of human thought

Collective action can change the world when it's deliberate and based in reason, but it can also become a mental trap, or a societal pressure valve.

Man, some people are just so dumb, I don't know if they're actually conscious. Sometimes I think their whole lives might be like a dream, they're just stumbling around, no idea what's going on, mumbling some random nonsense.
And the thing that you have to understand about our time period is that a lot of these people wield enormous power. They run whole countries and corporations.
We've handed over our civilization to people I wouldn't trust to tie their own shoelaces.
