Quixotry

Anyhow, this piece of Quixotry on your father's part, as it was unjust in itself, has brought forth a monstrous family of injustices.

He employs a range of terms; in addition to 'Cervantes,' 'Don Quixote,' 'Sancho Panza,' 'Dulcinea,' and 'Rozinante [sic],' I have found 'quixotic,' 'quixotism,' and even 'quixotry.' In keeping with this variety, his interpretation varies as well.

It can also be native to the antiquarian mentality; hence, the stereotype, ubiquitous in Scriblerian satire, of antiquarianism as intellectual quixotry, futile pursuit of history's lost causes.
