'Inference is considered to be a mere leap into the dark.' Which school holds this view?

The view that inference is a mere leap into the dark belongs to the Charvaka school.

The Charvakas are materialists who accept only perception as valid knowledge.

They argue inference rests on an unproven universal concomitance.

Since that concomitance can never be fully established, its conclusions are uncertain.

Treating inference as unreliable, they reject it as a blind jump.
