simpleminded

The simpleminded native is made the victim of the progressive white, who, by fair means or foul, deprives him of his country.

Would he have risked it, had he not been the most simpleminded of men?

And his simpleminded, untravelled, wonderloving auditor or auditors received his words literally.

Nothing had the girls (or the simpleminded 11 country Doctor who sped them) known of the dangers or pitfalls of the city.
