The word of the day is qualia:
- a quality, as bitterness, regarded as an independent object.
- a sense-datum or feeling having a distinctive quality.
"If I say fir and fescue
and clover and lover
whither identity and qualia?"
- Maureen M. McLane, "Mz N Enough", Spring 2016 The American Scholar (https://theamericanscholar.org/maureen-mclane-three-poems/#.VzZNQdm9LCQ)
