Nice clues composed with an art that will show intellectual discipline (7,7)

I believe the answer is:

natural science

'intellectual discipline' is the definition.
(scientific discipline)

'nice clues composed with an art' is the wordplay.
'composed with' indicates anagramming the letters.
'nice'+'clues'='niceclues'
'an'+'art'='anart'
'niceclues' anagrammed with 'anart' gives 'NATURAL SCIENCE'.

'that will show' acts as a link.

I've seen this clue in The Times.
