ideationally

Frighteningly, we who live here are not only practically affected, but also axiologically and ideationally infected.

I'm in the middle of noting to myself how you misused 'perceptively' (shoulda been perceptibly) when I get to a word I've never seen before: 'ideationally.'

To the Editor: In your Feb. 21 news article on the researchers who studied the writing style of 93 nuns when they were young women about to join an order, you say they found that the more grammatically and ideationally complex writers were less likely to develop Alzheimer's disease in later years.
