Cell 8, Duty: the count of eights and the sense of obligation

Cell 8 of the Psychomatrix, called Duty, is the cell that counts the eights. The school reads it as responsibility, kindness and honesty, from obligation not felt by default to self-sacrifice as a way of life; about four dates in ten leave it empty in both centuries.

A 3 by 3 square drawn 1 4 7, 2 5 8, 3 6 9, with the middle-right cell, 8, marked. Beside it a bar chart of the share of dates by the number of 8s: about 41 to 43 percent of dates have none and about 40 percent one; two 8s fall to about 15 percent.

Meaning

The eighth cell collects every 8, and the school reads it as duty: responsibility, kindness and honesty toward other people. An empty cell is read as obligation not felt by default; one 8 as responsibility at work before home; two as duty at the centre of the character; three as responsibility in excess and the truth told whether or not it helps; four as anticipating what others need; five or more as self-sacrifice.

In our own words, the cell describes how a person carries obligations, lightly or heavily, and whom they feel them toward.

Every count, in our words

The tradition's scale for a cell runs from none to overload. Our reading of each count of eights follows, with the share of dates that have it, over every day of the twentieth century and of the twenty-first.

  • 0. Obligation is not felt by default; the person takes more than gives until life asks otherwise. Dates: 41.3 percent of 1900 to 1999, 43.0 percent of 2000 to 2099.
  • 1. Responsible at work, slower to feel it toward the people at home. Dates: 40.3 percent of 1900 to 1999, 37.9 percent of 2000 to 2099.
  • 2. Duty at the centre: reliable, generous, truthful, and expecting the same back. Dates: 15.0 percent of 1900 to 1999, 15.8 percent of 2000 to 2099.
  • 3. Responsibility in excess: the truth told whether or not it helps. Dates: 3.1 percent of 1900 to 1999, 2.9 percent of 2000 to 2099.
  • 4. Anticipates what others need before they ask; care that can become control. Dates: 0.2 percent of 1900 to 1999, 0.4 percent of 2000 to 2099.
  • 5. Self-sacrifice as a way of life. Dates: under 0.1 percent of 1900 to 1999, under 0.1 percent of 2000 to 2099.
  • 6 or more. Overload: care that smothers, and moralising. Dates: no date of 1900 to 1999, no date of 2000 to 2099.

How often the cell fills

Eights come from days, months, years such as 1985 or 2008, and the working numbers. The average is 0.81 for the twentieth century and 0.80 for the twenty-first, and 41.3 and 43.0 percent of dates leave the cell empty. One 8 is the commonest count, two fall to about 15 dates in 100, three or more to about 3.

Ones into eights

The school pairs this cell with the first: it teaches that a surplus of 1s, a strong will, can turn into 8s, a sense of duty, and back again. That is its doctrine, recorded as the school's; we compute no transitions.

What this page leaves out

Alexandrov's school teaches transitions that touch this cell (11 to 8 and 8 to 11); we record them as the school's doctrine and compute none of them. Nothing here compares two people's squares. Births from 2000 are read on the classic formula, with the "+19" variant as a labelled option.

Correspondences

How the schools read it

Alexandrov's school and the Russian tools
Count the eights and read the count on the scale from none to overload; the cell is Duty.
Afisha and a few others
The same cell, drawn with 1 2 3 across the top instead of 1 4 7.
Practitioners of "+19"
For births from 2000, the third working number is the first plus 19, which changes the digits counted. A convention, offered by us only as a labelled option.
Templeton and Phillips
The Western birth chart counts only the date's digits and reads a line when its three cells are all full or all empty.
EsoTerrier
The cell describes how a person carries obligations, lightly or heavily, and whom they feel them toward.

Claims about it

  • The meaning of cell 8 goes back to Pythagoras.

    false

    What the record shows: Pythagoras wrote nothing, and no early source mentions a square of birth-date digits. The cell and its name come from the Russian tradition that Alexandrov's school fixed, in print from 1999.

  • The nine cell names come from antiquity.

    false

    What the record shows: The names character, energy, interest, health, logic, labour, luck, duty and memory are the Russian tradition as Alexandrov's school fixed them; calculators print them without saying whose they are.

  • Digits move into and out of cell 8 by fixed transitions (11 to 8 and 8 to 11).

    unverified

    What the record shows: A doctrine of Alexandrov's school, taught as a way of reading and strengthening the square, with nothing that tests it. We compute no transitions.

  • An empty cell 8 shows that a person is selfish.

    false

    What the record shows: No study of the square exists. The school's reading describes a temperament.

  • The "+19" rule is Alexandrov's own correction for births from 2000.

    false

    What the record shows: His provision for this century, as his followers summarise it, concerns how the lines are read. "+19" is a practitioner convention, and we offer it only as a labelled option.
