See the light without the 1st philosopher? (5)

I believe the answer is:

hegel

I'm a little stuck... Click here to teach me more about this clue!

'philosopher?' is the definition.
(German philosopher Georg Wilhelm Friedrich Hegel)

I don't understand the remainder of the clue.

Can you help me to learn more?

(Other definitions for hegel that I've seen before include "German philosopher, d. 1831" , "German 'dialectic' philosopher" , "Georg Wilhelm ---, Ger. philosopher" .)

I've seen this clue in The Irish Times.
