Hearers will accept what speakers say, and so speakers will reasonably expect hearers to accept, consider, or entertain what they say about objects or states of affairs not within the immediate perceptual vicinity of the interlocutors.

What is the meaning of entertain in the above sentence. The only meanings of the word that I could find (Source) and are relevant here are to receive and to consider. But those meanings are already there via words accept and consider. Is there any other sense that can be relevant here, and cannot be taken to be already given via words accept and consider?
