Can u please give me 2 own examples of contrariety,subcontrariety,subalternation,and,contradiction?PLEASE.

Sure! I can certainly provide you with examples of contrariety, subcontrariety, subalternation, and contradiction. Here they are:

1. Contrariety:
Contrariety refers to the relationship between two propositions where they cannot both be true, but they can both be false.

Example:
Proposition 1: All dogs are mammals.
Proposition 2: No dogs are mammals.

In this example, if proposition 1 is true, it contradicts proposition 2, and vice versa. However, if both propositions are false (e.g., if some dogs are mammals and some are not), then they would be considered contraries.

2. Subcontrariety:
Subcontrariety refers to the relationship between two propositions where they cannot both be false, but they can both be true.

Example:
Proposition 1: Some birds can fly.
Proposition 2: Some birds cannot fly.

In this example, if proposition 1 is true (some birds can fly), then proposition 2 must also be true (some birds cannot fly). However, if proposition 1 is false (no birds can fly), then proposition 2 must be true (some birds cannot fly). Therefore, they exhibit subcontrariety.

3. Subalternation:
Subalternation refers to the relationship between a universal proposition and a particular proposition, where the particular proposition must always be true if the universal proposition is true.

Example:
Proposition 1: All humans are mortal.
Proposition 2: Some humans are mortal.

In this example, if proposition 1 is true (all humans are mortal), then proposition 2 must also be true (some humans are mortal). However, if proposition 2 is true (some humans are mortal), proposition 1 cannot necessarily be true (it may or may not be the case that all humans are mortal). Therefore, proposition 2 is a subaltern of proposition 1.

4. Contradiction:
Contradiction refers to the relationship between two propositions where they cannot both be true at the same time, and they cannot both be false at the same time.

Example:
Proposition 1: The sky is blue.
Proposition 2: The sky is not blue.

In this example, if proposition 1 is true (the sky is blue), then proposition 2 must be false (the sky is not blue). Similarly, if proposition 2 is true (the sky is not blue), proposition 1 must be false (the sky is blue). Therefore, these propositions are contradictory to each other.
