This is what I found from 1952/2/1 watchtower p81,para14
Some of the speculating ones are more rebellious than others, disagreeing dogmatically with the discreet slave’s provisions, exalting themselves above the Lord’s established channel. They argue that the theocratic organization has not always been right, and that they once had ideas the organization rejected but now teaches, and thus imply that their present theories will likewise be accepted in time. They never mention the numerous speculations they have advanced in the past that were never adopted. That would spoil their campaign to get their present ideas gobbled up. What their conceit blinds them to is that the visible theocratic organization has never claimed infallibility, that it knows the message will be continually purified by the elimination of erroneous ideas, that it expects new truths to become manifest as more prophecies are fulfilled, that gradually the light will shine more and more until the perfect day, and that the clarifications will come through the discreet slave and not self-exalting speculators. (Prov. 4:18; Isa. 6:5-7; Mal. 3:1-3) It is a continuous process, for the slave is “to keep giving them their measure of food supplies at the proper time”. (Luke 12:42, NW) Doubtless some do have ideas that are not published until later; to do so earlier may have been premature, may not have been “at the proper time”. Wait upon the Lord.
