What is a necessary cause?
A component cause that must be present in every sufficient cause of a given outcome is referred to as a necessary cause.
For example, HIV exposure is necessary for AIDS to occur, and TB exposure is necessary for TB infection to occur..
How do you prove necessary and sufficient?
The assertion that a statement is a “necessary and sufficient” condition of another means that the former statement is true if and only if the latter is true. That is, the two statements must be either simultaneously true, or simultaneously false.
What are two types of causes?
We first distinguish between causes which are events (including actions) and causes which are states. Second, we distinguish between modifiable and non-modifiable states. This yields three types of causes: fixed states (non-modifiable), dynamic states (modifiable) and events (including actions).
What is the necessary?
Necessary, essential, indispensable, requisite indicate something vital for the fulfillment of a need. Necessary applies to something without which a condition cannot be fulfilled or to an inevitable consequence of certain events, conditions, etc.: Food is necessary to life.
What is the meaning of not necessary?
Not necessary means it is not essential but it is not an instruction to refrain from doing a thing.
What does when needed mean?
When needed – means you perform an action WHEN you need to. Examples: If you continue to feel pain, take a painkiller when needed. Add more pepper to the food if needed.
What is the meaning of sufficient?
adjective. adequate for the purpose; enough: sufficient proof; sufficient protection. Logic. (of a condition) such that its existence leads to the occurrence of a given event or the existence of a given thing.
What is a precipitating cause?
Precipitating Cause–forces the phenomenon to happen, this is the “last straw” idea, usually happens just before the phenomenon occurs. For example: in the case of a forest fire, the bolt of lightning would be the precipitating cause. Remote Causes–the causes are remote in time, they are causes of causes.
What is the difference between a conditional and an argument?
Conditionals, Arguments and Inferences The difference is that when you put forth an argument you commit yourself to the truth of all its parts–even if “only for the sake of the argument.” When you assert a conditional, however, you do not commit yourself to the truth of either its antecedent or its consequent.

What is an Inus condition?
An INUS condition is where a ‘… cause is, and is known to be, an insufficient but necessary part of a condition which is itself unnecessary but sufficient for the result’ (Mackie 1965: 247). His classic example is that of a fire that breaks out in a house.

What does if and only if mean?
In logic and related fields such as mathematics and philosophy, if and only if (shortened as iff) is a biconditional logical connective between statements, where either both statements are true or both are false. … In logical formulae, logical symbols are used instead of these phrases; see the discussion of notation.
Can something be sufficient but not necessary?
A sufficient condition is only one of the means to achieve a particular outcome. This means that there could be other means to achieve the outcome. Therefore, a sufficient condition is not necessary to be fulfilled in order to achieve the desired outcome.
What is the difference between sufficient and necessary?
A necessary condition is a condition that must be present for an event to occur. A sufficient condition is a condition or set of conditions that will produce the event. A necessary condition must be there, but it alone does not provide sufficient cause for the occurrence of the event.
Is the only sufficient or necessary?
Example 2: It’s important to remember that “only,” “only if,” and “only when” all introduce the necessary condition. These “necessary condition prompters” should not be clumped together with the notorious “the only.” “The only” will introduce the sufficient condition.

What is a necessary and sufficient cause?
Cause/Causation. … Causation is the relationship that exists between cause and effect. Necessary Cause – the event(s) without which the consequence cannot occur. Sufficient Cause – any event which is always followed by the consequence.
