incoherence

The quality of being incoherent.

HE DESCENDED, signifieth a voluntarie motion, where as the bodie dead hath neither WILL nor MOTION. […] Though therefore this exposition cannot be charged with falsitie, for Christ was trulie buried; yet may it not bee endured by reason of […] the improprietie and incoherence of the worde, that a deade corps should descend […]

1680, Henry Care, The History of the Damnable Popish Plot, London: B.R. et al., Chapter 23, Section 2, p. 327, […] the said Lane is prevailed with […] to prefer an Indictment against Dr. Oates, for attempting to commit upon him the horrid and detestable sin of Sodomy; but the Grand Jury, by reason of the incoherence and slightness of his Evidence, did not think fit to finde it, but returned an Ignoramus.

The quality of being incoherent.

1669, Robert Boyle, “The History of Fluidity and Firmness,” Section 16, in Certain Physiological Essays and Other Tracts, London: Henry Herringman, p. 182, […] if it [Salt-Petre] be beaten into an impalpable powder, this powder, when it is pour’d out, will emulate a Liquor, by reason that the smallness and incoherence of the parts do both make them easie to be put into motion […]

Something incoherent; something that does not make logical sense or is not logically connected.

[…] Incoherences in Matter and Suppositions, without Proofs put handsomly together in good Words and a plausible Stile, are apt to pass for strong Reason and good Sense, till they come to be look’d into with Attention.

This was strangely heightened at times by the ragged Elijah’s diabolical incoherences uninvitedly recurring to me, with a subtle energy I could not have before conceived of.

Thinking or speech that is so disorganized that it is essentially inapprehensible to others.
