This is the symbol for secular humanism:

secular humanism as demonstrated during the renaissance.

"Non-secular Humanism" is generally referred to as plain old "humanism", which is much the same thing, but can include spirituality and lesser deist beliefs, such as agnosticism. It does not exclude secular humanists, but many are inclined to include the "secular" part in order to be clear on the atheistic nature of their moral and ethical beliefs.

And post modern secular humanism denies ultimate truth itself.
