Loneliness can be depressing, but it may have helped humans survive
Evolutionary Psychology is like Leibnitizian Optimisim [<a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Best_of_all_possible_worlds" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Best_of_all_possible_worlds</a>] where God is replaced by evolution.  It does nothing to aid in our understanding except to reassure us that everything that is is as it should be.  It&#x27;s essentially an ideology of apathy.<p>Leibnitz&#x27;s Argument goes like so:<p>&gt;1. God [Evolution] has the idea of infinitely many universes.<p>&gt;2. Only one of these universes can actually exist.<p>&gt;3. God[Evolution]&#x27;s choices are subject to the principle of sufficient reason, that is, God[Evolution] has reason to choose one thing or another.<p>&gt;4. God[Evolution] is good.<p>&gt;5. Therefore, the universe that God[Evolution] chose to exist is the best of all possible worlds.[1]<p>FYI, Voltaire made a nice parody of this ideology in his book Candide.
