It&#x27;s interesting that scientists talk about animals displaying &quot;anxious behavior,&quot; rather than &quot;being anxious,&quot; because we don&#x27;t &quot;know&quot; what&#x27;s actually going on in their minds.  But we&#x27;re perfectly willing to believe that none of our fellow humans are philosophical zombies[0], even though we don&#x27;t know other people&#x27;s true state of mind, or if they even have a state of mind, anymore than we know about rats&#x27; or cats&#x27;.<p>[0]<a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Philosophical_zombie" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Philosophical_zombie</a>
