I used to read dictionaries a lot, but my poor memory has convinced me the effort is futile. I tend to mirror the usage I percieve around me.

For this word, here are examples of how I might use it:

"Neither programmer nor their creations are, per se, logical."

"Pluto should not be considered a planet, per se, lest we should consider every bit of dust wandering about in our vicinity similarly."

"Life does not require exact reproduction, per se."
