Clarification about sufficient and necessary

Is it true that the sufficient part of statements are more specific in nature and necessary are more general? From the example that you have given it seems like that is the trend but does that always hold true?

Hi Avif, thanks for the question.

It may seem that way much of the time. This is because the necessary condition is often a more basic requirement for the sufficient.

E.g. If water, then hydrogen and water.

Water is more specific, but hydrogen and water is more general.

However, there is not necessarily any rhyme or reason with specific vs generality of sufficient and necessary. Take for example the following:

If you are human, then you like green gummy bears.

Sufficient here is very general and the necessary is very specific.

I would just focus on the structural aspects of the statements you are working with and find the indicators of sufficient and necessary condition.

I hope this helps. Please let me know if you have any other questions.

The example that you give seems to be not true but it could be used within the logic of S and N logic and therefor would not work with the way I am framing it. I think I got it. Thanks!
