If all of this, all the life of a stream of water, can be nothing but a pile of atoms, how much more is possible?
One does not, by knowing all the physical laws as we know them today, immediately obtain an understanding of anything much. I love only nature, and I hate mathematicians.
There’s plenty of room at the bottom.
By honest I don’t mean that you only tell what’s true. But you make clear the entire situation. You make clear all the information that is required for somebody else who is intelligent to make up their mind.

If we want to solve a problem that we have never solved before, we must leave the door to the unknown ajar.
If we will only allow that, as we progress, we remain unsure, we will leave opportunities for alternatives.
