2.4.2 Possessive Conditional Specification Assumptions
Take the sentences:
• “A family has parents and children.”
• “John is a parent of Pete.”
Two comments about the first sentence:
1. This sentence has a prior term of the possessive verb “to have”;
2. The conjunction “and” indicates that both specifications are necessary to validate the definition (condition).
Two comments about the second sentence:
1. We can read this relational specification as “John” has a “parent(al)” relation with “Pete”;
2. However, the reverse relation(ship) from “Pete” to “John” is unknown, in which case we may not make any conclusions about “Pete” although we would like to claim that:
• “Pete is a child of John.”
• “John has a child (named Pete).”
However, we would still like to do something with this information as it can provide a wealth of information, if the above mentioned assumptions about “Pete” are true. If these assumptions prove to be false, there is in any case clarity created in the situation and the information can be more specified, which we strive to realize.
We may make possessive conditional specification assumptions:
1. When there is a prior term of the possessive verb “to have” is used;
2. When there is a conditional specification collection;
3. By using the word, “children”, a relationship with “parents” is at the moment the only possible relation that can be reversed;
4. If later on other relationships appear possible, the assumptions in question will need to be tested;
5. If we take all conclusions, that can be deducted from an assumption, and name them assumptions until the assumption is confirmed or not, then all primary assumptions must be revisited;
6. If an assumption is confirmed, then it receives the status of a conclusion or proof;
7. If, on the basis of a compound specification substitution, a conclusion can be made, then we do not call this an assumption but a question.
