I believe the answer is:

tautologic

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

'like a lazy indolent slacker say given no slack' is the definition.
I can't judge whether this definition defines the answer.

'branch of philosophy' is the wordplay.
'branch' becomes 'taut' (I can't justify this - if you can you should give a lot more credence to this answer).
'of' becomes 'o''.
'philosophy' becomes 'logic' (logic is a kind of philosophy).
'taut'+'o'+'logic'='TAUTOLOGIC'

'over' acts as a link.
