A great read I enjoyed was The Anubis Gates by Tim Powers.
Less philosophy and more historical romp.
Time travel, body swapping and even the Romantic poet Coleridge play a part.
I liked the way the time travellers identified each other by whistling 'Yesterday (all my troubles seemed so far away)'

And not really part of a series but another Tim Powers book...

The Drawing of the Dark.
This one has someone who might or might not be Merlin. The irish mercenary Brian Duffy might or might not be the once and future King, They are holed up in Venice as the Turks have just taken Vienna and theres nothing to stop them taking the rest of Europe. A longboat rows up the Grand Canal, some ancient Vikings have arrived looking for Ragnarok.
In the meantime everyone waits for the perfect time to crack the barrel of Herzwesten Beer.
