__Major premise__:
R is a complete and (complemented by S) a contingent cause of Q:

**(i)
If R, then Q;
**

(ii) if notR, not-then Q;

(iii) where: R is possible.

**(iv)
If (notR + notS), then notQ;
**

(v) if (R + notS), not-then notQ;

(vi) if (notR + S), not-then notQ;

(vii) where: (notR + notS) is possible.

__Minor premise__:
P is a complete and necessary cause of Q:

**(viii)
If P, then Q;
**

(ix) if notP, not-then Q;

(x) where: P is possible.

**(xi)
If notP, then notQ;
**

(xii) if P, not-then notQ;

(xiii) where: notP is possible.

__Putative conclusion__
is P a complete or (complemented by S) a partial cause of R?

NO! P is not implied to be a complete cause of R:

If P, then R? | denied by (vi) + (xi); |

if notP, not-then R | implied by (iv) + (vii) + (viii); |

where: P is possible | same as (x). |

Nor (complemented by S) a partial cause of R:

If (P + S), then R? | denied by (vi) + (xi); |

if (notP + S), not-then R? | open; |

if (P + notS), not-then R? | denied by (iv) + (viii); |

**Evaluation of mood # 344.**

__Major premise__:
Q (complemented by P) is a partial and contingent cause of R:

**(i)
If (Q + P), then R;
**

(ii) if (notQ + P), not-then R;

(iii) if (Q + notP), not-then R;

(iv) where: (Q + P) is possible.

**(v)
If (notQ + notP), then notR;
**

(vi) if (Q + notP), not-then notR;

(vii) if (notQ + P), not-then notR;

(viii) where: (notQ + notP) is possible.

__Minor premise__:
Q (complemented by S) is a partial and contingent cause of P:

**(ix)
If (Q + S), then P;
**

(x) if (notQ + S), not-then P;

(xi) if (Q + notS), not-then P;

(xii) where: (Q + S) is possible.

**(xiii)
If (notQ + notS), then notP;
**

(xiv) if (Q + notS), not-then notP;

(xv) if (notQ + S), not-then notP;

(xvi) where: (notQ + notS) is possible.

__Putative conclusion__:
is P (complemented by S) a cause of R?

NO! P is not implied to be a complete cause of R:

If P, then R? | denied by (ii) + (xiii); |

if notP, not-then R | implied by (iii)+(ix), or (v)+(x), or (v)+(xiii)+(xvi); |

where: P is possible | implied by (ii), or (iv), or (vii) + (xiii), or (ix) + (xii), or (xiv) or (xv). |

Nor (complemented by S) a partial cause of R:

If (P + S), then R? | denied by (ii) + (xiii); |

if (notP + S), not-then R | implied by (v) + (x); |

if (P + notS), not-then R? | denied by (i) + (xiii); |

where: (P + S) is possible | implied by (ii) + (xiii), or (vii) + (xiii), or (ix) + (xii), or (xv). |

Nor a necessary cause of R:

If notP, then notR? | denied by (vi) + (ix); |

if P, not-then notR | implied by (i)+(ix)+(xii), or (i)+(xiv), or (vii)+(xiii); |

where: notP is possible | implied by (iii), or (vi), or (viii), or (x), or (xi), or (xiii) + (xvi). |

Nor (complemented by S) a contingent cause of R:

If (notP + notS), then notR? | denied by (vi) + (ix); |

if (P + notS), not-then notR | implied by (i) + (xiv); |

if (notP + S), not-then notR? | denied by (v) + (ix); |

where: (notP + notS) is possible | implied by (iii) + (ix), or (vi) + (ix), or (xi), or (xiii) + (xvi). |

(Similarly, *mutadis mutandis*, for **mood

__Major premise__:
Q is a complete cause of R:

**(i)
If Q, then R;
**

(ii) if notQ, not-then R;

(iii) where: Q is possible.

__Minor premise__:
Q is a complete and (complemented by S) a contingent cause of P:

**(iv)
If Q, then P;
**

(v) if notQ, not-then P;

(vi) where: Q is possible.

**(vii)
If (notQ + notS), then notP;
**

(viii) if (Q + notS), not-then notP;

(ix) if (notQ + S), not-then notP;

(x) where: (notQ + notS) is possible.

__Putative conclusion__:
is P a necessary cause of R?

NO! P is not implied to be a necessary cause of R:

If notP, then notR? | open; |

if P, not-then notR | implied by (i) + (viii); |

where: notP is possible? | implied by (v), or (vii) + (x). |
