Epicurus

Interesting quotye
Don't fear god,
Don't worry about death;
What is good is easy to get, and
What is terrible is easy to endure.
—Philodemus, Herculaneum Papyrus, 1005, 4.9-14
from http://en.wikipedia.org/wiki/Epicureanism
This does seem to be some of Freud's theories.
and then the article goes on to say
In the Jewish exegetical tradition, the word "Apiqoros" (אפיקורוס) appears in Rabbinical literature as a reference to those who lack religion or are ostensibly atheistic. Its origins are uncertain, but it may have originally referred specifically to the Epicurean philosophy, although it eventually came to refer to any philosophy lacking a God or a God-based morality. It is also occasionally used to describe heretic principles or heretics themselves. The word is still used in modern Hebrew, mainly among religious Jews.
