Risk comes from not knowing what you are doing so wide diversification is only required when investors are ignorant. You only have to do a very few things in your life so long as you don't do too many things wrong.
Each nation knowing it has the only true religion and the only sane system of government, each despising all the others, each an ass and not suspecting it.
Therefore we pledge to bind
ourselves to one another, to embrace
our lowliest, to keep company with
our loneliest, to educate our illiterate,
to feed our starving, to clothe our
ragged, to do all good things,
knowing that we are more than
keepers of our brothers and sisters.
We are our brothers and sisters
As long as God does not intervene in the contemporary universe in such a way as to violate physical laws, science has no way of knowing whether God exists or not. The belief or disbelief in such a Being is therefore a matter of faith.
