The man was born in 1892, a product of the patriarchy. In a sense, he was writing about the father he never really had, the good father in Gandalf, the bad father in Denethor. We see echoes of his mother in Queen Galadriel, Lady Melian and even Eowyn - women of courage, stature and power.

In Aragorn we see the Good Son. But this good son, the Heir of Isildur, King of Men, was raised by a single mother! Tolkien didn't make a big thing of that in his books, any more than he did of his own deep Christianity. He abhorred allegory and was not writing social commentary.

The nearest he came to putting his own beliefs and ideas into the books was his lyrical desciption of the pastoral idyll that was Hobbit society. He was a medievalist and pastoralist who felt that urban industrialisation and technology was the worst thing for mankind.

For the rest, he wrote in the mode of legend and chivalric romance. The passionless love of Aragorn and Arwen represents in some ways the ideal of courtly love. Instead of taking Arwen to bed, Aragorn wins a throne for her!

But then Tolkien himself had only one true love in his entire life.
