Radical skepticism, doubt, and uncertainty

Skepticism is healthy, but don’t forget what we do know.

If you always focus on what we don’t know, you may already worship uncertainty.

Doubt is useful; radical doubt is self-consuming.

Radical doubt easily infects others. It is fairly easy to implement: simply find a gap in the scientific evidence on some topic, and use it to initiate a shadow of doubt in the minds of others. Radical doubt takes hold when a shadow of doubt becomes all-encompassing darkness.

Radical skepticism begets more radical skepticism.

Assertions of radical doubt:

“Since evolution could be false, God exists.”

“There is no scientific consensus on general brain function, so there must be a non-physical soul.”

“Neuroscience cannot ever explain consciousness because explaining consciousness is really really hard.”

“I cannot imagine how neuroscience could explain consciousness, so neuroscience cannot ever explain consciousness.”

“I think, therefore I am.” (cogito ergo sum)
