Is preception all we need in life?

That's all anyone has, and it's all subjective to the individual.

Does our brainwashing cause our subjective perceptions? Will who and what we are today ever change, see the light, or get an Epiphany?

When we remember we are all mad, the mysteries disappear and life stands explained. Mark Twain

All of that

We also need to be brainwashed so we can fit into the behavior patterns of the rest of the world, myself included.

“You want people walking away from the conversation with some kernel of wisdom or some kind of impact.” Henry Dean Stanton
