Linguistic evidence sufficient for good inductive inference
An inductive inference that a machine can think can be made by considering only linguistic behaviour; even if this inference needs to be revised later in the light of further evidence. Inferences made without full evidence are common in science.
Otherwise:
"scientists would never gather enough evidence for any hypothesis."
James Moor, 1987, p.1128.
