One commentator on Chris Huff’s Video states “I’m not sure that Davey’s method does reflect Ebbinghaus, but it seems to work anyway”. True or False?

True. It is only a working approximation to Ebbinghaus. Supermemo and Anki can get on his curve much closer, but the problem is in order to work they repeat material you really already know and this method enables you to skip writing that again, thus focusing only on the unlearned material. In order to achieve that economy, I have a working approximation to the curve, which works on reiteration of unlearned material. Like scissors cutting the hair too long but then cutting again until you get what you want versus electric shears with a set depth which might not be precisely the depth you wanted and only work if a short cut is desired, and the shears won’t work at all unless you have electricity.

It’s harder to see the curve that it is with the Supermemo algorithm, but by the application of the 14 days with iteration, you do cover the same thing, only with less work and less risk of switching on more short-term memory.

In addition to that I have a scientifically untested hypothesis which is divergent from Ebbinghaus, namely that short-term memory and long-term memory are distinct functions, the one happening when we remember consciously and the other when we allow it to function like breathing when we forget about it. This idea is my own conclusion from non-scientific observation of my own case and the case of users.

The number of contented users of GLM who keep going with it into repeated projects year on year, some of whom have done as many if not more than I have and probably will end up doing much more, proves that the method certainly works, it works probably regardless of people’s views about their own learning type as long as they at least enjoy the process of writing.

In short you’ve made a fair comment about the relation of Ebbinghaus. I want to acknowledge the input of what I learned from Ebbinghaus, but you correctly note it doesn’t stop there.

Not enough real science has been done with memory and if anyone wants to fund or test in a real university setting the hypotheses underlying the GLM then I’m happy to be involved.

The Psalms of Davey #10 – “O blest and only Potentate”

This is the tenth of my cycle of ten Hymns, called “The Psalms of Davey”. They are being reproduced in a special category on this blog one after another. In only one case is the tune my own (that’s this one – number ten). In other cases, please follow the links to get to the midi for the tunes, courtesy of To find the category of “Psalms of Davey” please review the categories section in the side bar.


(Words and music, Uncle Davey, Cambridge, 1986. Tune name “Alexandra”.) In fact this is the only one of the hymns where I prefer my own tune, Alexandra, which is an 8888 metre tune.

At the moment I don’t have a version of the tune Alexandra to upload.

My suggested chord progression, if the melody starts on E, is C, C, d, e, C / C, G, e, F, G7 / d, d, e, F, G7 / d, F, d, F, C, (G7).

The hymn was written as a one-off, at a different time, rather later than the others, after it seemed that I had stopped writing hymns. I did not even keep it over the years in the same book with the others. Nevertheless, it must be evident that it is much of a muchness with the other hymns written by me, possibly the best of them from a poetic viewpoint, with much theology. Probably if someone felt they could take only one hymn from my collection and add it to a hymn book for use in churches, I suppose I would most rather that this one were chosen, especially as it has its own tune, with number six as possibly second choice.

As befits a closing hymn, this one is based on a New Testament doxology, in this case a pauline doxology for Timothy, that tells us among many other verses that Christ is God. If you have been looking at all the hymns from the beginning of the collection to this, the end, thank you for your patience in bearing with me. I consider it a tremendous priviledge to have a readership, and am always delighted with any feedback, either by mail or on the comments section.  Another project I have in mind for the future is a page linking to my most favorite hymns of all time.

God bless, and please enjoy the articles and other parts of my site.

O blest and only Potentate,
Thou King of Kings and Lord of Lords
I look unto Thy mercies great
And I am lost, am lost for words.

Thou didst in kindness set Thy love
Upon this wicked soul of mine
E’en or Thou camest from above
E’en or the sun, the sun did shine.

Thou hast in anguish lovéd me
When beat the sun upon Thy brow
When nailéd to the accurséd tree
For me at Calvary wast Thou.

T’was then all bleeding on the rood
That Thou didst mine atonement make
Thou didst eclipse the wrath of God
In dying, dying for my sake.

Although Thou righteous art alway
And glorious in Thine holiness
Yet didst Thou take my plague away
And clothe me, clothe me in Thy dress.

Christ, Thou hast scanned mine inmost thought
Yea, known mine every grief and care
And  Thou hast intercession wrought
And holy, spotless made my prayer.

Shall I not say; Thou art my King?
My Lord and God I shall adore
Thy name proclaim, thy glories sing
Henceforth, till death, and evermore.


“I give thee charge in the sight of God, who quickeneth all things, and before Christ Jesus, who before Pontius Pilate witnessed a good confession; That thou keep this commandment without spot, unrebukable, until the appearing of our Lord Jesus Christ: Which in his times he shall shew, who is the blessed and only Potentate, the King of kings, and Lord of lords; Who only hath immortality, dwelling in the light which no man can approach unto; whom no man hath seen, nor can see: to whom be honour and power everlasting. Amen.” (1 Timothy 6 vv 13-16)
