Some of the answers above seem to assume that if an indefinite article is used with a noun, it must be a count noun usage. However, there may or may not be the possibility of using other count quantifiers / plural inflections with such words in given contexts:
I just have a love for finer food.
There are two great loves in my life: fine food and classical music.
*I have loves for finer food and classical music.
*She received three educations.
In an article at Useful English is found:
In formal writing and literary works the article a/an may be used with
some uncountable abstract nouns to show an unusual or temporary aspect
of something. The indefinite article here has similar meaning to:
such, certain, special, peculiar.
Compare these examples.
Formal / literary style:
The director spoke at the meeting today with an enormous enthusiasm.
A paralyzing horror overwhelmed him.
She smiled at us with an unusual friendliness.
Standard / everyday style:
The director spoke at the meeting today with great enthusiasm.
He was paralyzed with horror.
She smiled at us with unusual friendliness.
Accepting this, the 'count / noncount' divide is blurred in that an indefinite article is not proof of a count usage.
That having been said, I think that the answers given by Cord and Flater above, with education being considered countified in the sense of 'instance of', fit better here.
