We know that Karl Marx made fun of eighteenth-century robinsonades like Rousseau’s. Marx said that the origin of the social can by no means be a state of nature where isolated men finally come to meet and form a community. Solitude cannot be the origin of society. ...

Thomas Clark (1666):
But being thus constrain’d to house-abode,
And so withheld from following work abroad,
Also of all things else almost bereft,
This yet some solace was and comfort left,
That though debarr’d Society with me,
I still might have converse with Book and Pen: [...]
And such good Books I had (though read before)
I now found time enough to re-read o’re,
With profit too (I hope) for Information,
Which may conduce to practice[al] Conversation.
This studious course, to which I was inclin’d,
Diverted many sad thoughts from my mind
And thereby did that saying versify,
'When most alone, then least alone was I.'
