The actual quote seems to have a rather different meaning:

Ledi Sayadaw wrote: Know, Perceive, Conceive, and View
Those who cannot differentiate the four elements in the head and who do not know that solidity, etc., in the head are elements, know the head as such only; they note it as the head only; they only think that it is the head; and they see it as the head only.
To know that it is the head is a delusion of mind (citta).
To perceive that it is the head is a delusion of perception (saññā).
To conceive that it is the head is a delusion of conceit (māna).
To view it as the head is a delusion of view (ditthi).
