This haecceity

Don't let them tell you there's no such thing as this...

"Haecceity hek-see'i-tee, n (Latin, from haec, this) The aspect of existence on which individuality depends; the hereness and nowness of reality. First coined by the philosopher Duns Scotus, haecceity is that sense one gets of being in the present tense, the pure experience of a single moment in time. No other word has such subtle connotations. In addition, it sounds and looks very interesting." From the Phrontistery, a site about words.

Not my favourite word, but my favourite meaning.
