Notice Russell says we need charity and tolerance to survive on the planet. Here is a man from a family born through a product of centuries in aristocracy making the philosophy about life. I find it rather amusing.
So, I must tolerate a culture that only accepts a particular believe, or I get my throat cut, or sent to get incinerated, or be terrorized by someone with a belief and if I dont want that belief they will explode in front of me, or better create laws that keep me in the box to be poisoned unless my behavior is changed, as in the current Schrödinger cat culture.
The aristocrat knows very well that being born in life a person can be so awkward in mental fidelity that the soul is essentially broke to being with.
To be able to understand this is part of the new age in communication and education. Moreover it is the very deep sense in a new self-taught Internet environment. Actually this is what self-evident is about at any higher education. Try reading Russells History of western culture a pdf file careful it is 955 pages long.

Anyway Russell brings out the significance in the American declaration where we hold these truths to be self-evident. An incredible philosophy that originated back to ancient times in Greece. Again where Democracy was dominated and had to deal with the wealthy class.
In this age Americans and those connected online are witness to a cultural sense that is unlike any in previous history. This is the age of a common sense that belonged to those aristocrats that held information close to the vest. But many with money are having a difficult time to accept change it is self-evident by the ignorance taught and reported by our modern politicians and modern media.
