perceptivity

Working in the Reading Room with me would be Ina, whose thoroughness and perceptivity in doing research I had learned to trust.

It had come to him in a flash of unusual perceptivity that if he did not seize this moment which her softened mood generously offered for effecting a reconciliation, another opportunity might not present itself.

Through his prodigious emotional perceptivity he has the power of feeling and making us feel some strange, perverse accident of fate, destructive of the individual—of making us feel it to be real and terrible.

His failure would be no indictment either of his perceptivity or of the merit of the work of art.

I could take no credit for my perceptivity since everyone in San Diego knew as well as I that this was no duplicate freak, but the same, the identical, the fearsome grass.
