Stumbled on this and really liked it:

The opposite of love is not hate, it’s indifference.

The opposite of art is not ugliness, it’s indifference.

The opposite of faith is not heresy, it’s indifference.

And the opposite of life is not death, it’s indifference.

Elie Wiesel (1986)

This chimes with my practice. It is easy to take the equanimity of Buddhism (upekkhā) to be a kind of laid back indifference when the opposite is the case.  The combination of the four Brahmavihara (loving-kindness, compassion, sympathetic joy and equanimity) plug us into experiencing life to the full.
