Argument from Conscience

[Angrboda]

...Naturalism offers no value, no meaning, just depression and despair...

You may say, "I don't know" but when facing tough questions in life, the answers that a naturalistic framework offer are bleak.

The answers that certain interpretations of naturalism offer are bleak.  There are positive interpretations of naturalism, but even if there weren't, turning aside from naturalism because you haven't found comforting answers in it is a lot like turning away to "godidit" because the answers to the origin of the universe aren't forthcoming.  Both moves put an end to inquiry.  If naturalism appears bleak, turning your back on the quest for answers is even bleaker.  It assures failure by putting a stop to seeking.

The Vinegar Tasters, is a traditional subject in Chinese religious painting. The allegorical composition depicts the three founders of China's major religious and philosophical traditions: Confucianism, Buddhism, and Taoism. The theme in the painting has been interpreted as favoring Taoism and critical of the others.

The three men are dipping their fingers in a vat of vinegar and tasting it; one man reacts with a sour expression, one reacts with a bitter expression, and one reacts with a sweet expression. The three men are Confucius, Buddha, and Laozi, respectively. Each man's expression represents the predominant attitude of his religion: Confucianism saw life as sour, in need of rules to correct the degeneration of people; Buddhism saw life as bitter, dominated by pain and suffering; and Taoism saw life as fundamentally good in its natural state.
