Because in a day chart Jupiter has zero essential dignity at 23 Aries. He is therefore peregrine.
Yes, I agree with you Tom that Jupiter being in a day chart has zero at 23 Aries, but it is also received by Sun in 24 Gemini (sextile, Sun being sinister)
Peregrine planets are weak.
That is true according to your theory.
Jupiter could be weak only in the sense that he isn?t able to act according to his nature.
All the accidental dignity in the chart can?t make an essentially weak planet strong.
Ignoring the different opinions on whether the essential dignity is an indicator of strength or not:
I see that you link accidental dignity with essential dignity.
But I wasn?t able to find the nature of this link.
Now essential dignity is connected to zoidio. accidental dignity is connected to houses, or to relations between planets and sun, etc.
1. On one hand you could say that essential dignity is the general and accidental dignity is exception. But in order to say that, you should have both of them establishing rule to the same reference level, which is not the case. The essential dignity is connected to zoidio and accidental dignity for example, in the case of angularity, to houses. So different plans.
But if so, the accidental dignity could be an exception to essential dignity.
2. On the other hand you could say that essential dignity is the exception and accidental dignity the rule. Ignoring the etymology of the word accidental, you should observe again the differences between zoidio and houses.
3. Last but not least, you could say that essential dignity is the ideal model of dignity, in some way a prototype from the ?mundus imaginalis ? (from Henry Corbin, the Arabic correspondent would be ?alam al khayal?; I don?t know for sure the exact word in english but surely isn?t about imaginary, or fantastic or something like this), and accidental dignity the reality (don?t understand from this, that the mundus imaginalis is not real, differences is about manifestation and essence) of sublunary world, condemned to permanent change, but helped in some way by eternal cycle. So from this perspective (which is, I think, the most interesting) we would find ourselves, in some way, in the first situation. And again the accidental dignity could be an exception to essential dignity.
Conclusion. Why all the accidental dignity in the chart can?t make an essentially weak planet strong?
Pardon me. That?s not a conclusion.
This isn't difficult, and it isn't arbitrary or subject to opinion. Essential dignity can be determined quickly, and accurately in any chart
I congratulate you!!!
Once more: the almuten has a defintion. This definition is not subject to opinion. It is clear as day.
Watch out not to confuse definition with the technique of finding almuten, or even worse, with almuten effects.
And by the way I thought that it was a subject to opinion. The prove is that we do mistakes (aren?t we told from childhood to death what is wrong or what is right?

)
But if you wish I will not make any remarks about your opinions.
