It seems that all three of these have never been “put out there.” So, with little explanation or elaboration:
The First Educational Metaphor
While labeled differently, this was previously discussed in https://www.celestial.life/2016/05/educational-system-metaphor/
What man upon receiving a PhD looks with derision upon a kindergartner, knowing that his knowledge is superior?
The Second Educational Metaphor
Context: based upon my prior understanding of the COJCOLDS beliefs and doctrines, the “lesser law” (i.e., the law of Moses) was highly disparaged for its inferiority to and then replaced by the “higher law” as taught by Christ. This scripture was interpreted as meaning that the Mosaic Law was dead (“canceled”, kaput, irrelevant):
For behold, the covenant which I have made with my people is not all fulfilled; but the law which was given unto Moses hath an end in me.3 Nephi 15:8
This now seems to be a ridiculous interpretation. Do we discard Luke 10:25–28?
One cannot master calculus without utilizing arithmetic, algebra, and trigonometry.
Clearly this is related to the first. Shouldn’t we rather think in terms of the amazing things we can do with arithmetic once we have mastered calculus?
Curiously, we do not disparage the Aaronic Priesthood once obtaining the Melchizedek. Neither do we set aside the covenants made at baptism when we receive the higher ordinances that follow.
Note: there is another way to interpret the aforementioned scripture: a temporarily employed structure may be used to help build a greater structure (e.g., bridge, archway, tall building). At the end of the project, the temporary structure is dismantled, leaving the intended structure to stand alone.
The preference for the prior comes from a yet incomplete understanding of being taught. Reference: https://www.celestial.life/2017/09/upon-the-mountain-2017-8-21-part-2-of-4/
The Third Educational Metaphor
To be an engineer, first there was college and a great deal of learning. Eventually, the learning coupled into a network of understanding. Somewhere in there was a degree or certificate. Then understanding expanded by doing the work of an engineer. After much repetition, almost miraculously, one finally thinks like an engineer, behaves like an engineer, and truly becomes an engineer. Then, and only then does one truly know what it is to be an engineer.
This is probably true of many professions. It is true of motherhood, fatherhood, and the list goes on.
Know by being Be by doing Do by understanding Understand by learning
This is a reformulation, which may require further reformulation.
Here we elevate the word know to something of far greater degree. Implicit is that to fully know the Father, one must be like the Father, having done that which the Father has done, etc. In that sense, only Son Ahman knows Father Ahman, but even that isn’t complete until such time as Son Ahman watches Grandson Ahman, who…. Implicitly, perhaps the knowledge is always incomplete.
But, to be like God, one must do those things that God does (or did?). At our level, we presume this means continuing that process by being obedient to the understanding with which we are blessed.
There are so many more things that might be written, but this is sufficient. The remainder are commensurate and reasonably obvious.
