Man becomes man only by his intelligence, but he is man only by his heart.
Henri Frederic Amiel

After all, it is the divinity within that makes the divinity without; and I have been more fascinated by a woman of talent and intelligence, though deficient in personal charms, than I have been by the most regular beauty

Washington Irving

This one is a bit long, but I liked it.

Beauty without intelligence is an illusion that is close to disenchantment. It is like a fairy that fascinates us, as long as we look at her through the enchanting prism of her beauty. However, it disappears as soon as the light of reason penetrates beyond the place where the eyes can see.

-Mercedes Cabello de Carbonera, Concerning Women's Intelligence and Beauty, 1876

I can't find anything specific to what you're looking for, but how about "beauty comes from within"

stardust · Kenneth Cole

"Beauty without intelligence is a masterpiece painted on a napkin" anonymous

I love the de Cabonera quote that tri_sarah_tops posted.
