In this video, I will explain the difference

between a deductive and an inductive argument. So, broadly speaking, we can separate arguments

into two different types. The first type are deductive arguments. These are arguments whose

conclusions follow, or appear to follow, necessarily. All teachers are funny. Karin is a teacher.

Therefore Karin is funny. If all the premises are true, then the conclusion must also be

true. It must be true. Necessarily. Versus an inductive argument. This is an argument

whose conclusions follow, or appear to follow, probably. So, if we say 90% of teachers are

funny, and then we say Karin is a teacher, then we can conclude that Karin is funny. But we don’t know that for certain, because

she could be in that 10% of teachers who aren’t funny. So, whereas in the first argument,

if all teachers are funny, and if Karin is a teacher, well, then Karin must necessarily

be funny. But in the second argument, since only 90%

of all teachers are funny, um.. Then there’s a 90% chance that Karin is funny.

But there’s a chance that she is not. So, we’re gonna be interested- we’re not gonna

make a lot out of this distinction, I just want you to be aware that these two types

of arguments exist. And the type of argument we’re gonna be looking at exclusively are

the deductive arguments. So if you’re looking at inductive arguments, that is a different

branch of logic than we will be doing in this class. So we will be focusing on the logic of deductive

arguments. So, its important to know the distinction, just so that we know what we’re dealing with.

Thanks

Creative explanation and i was searching to stabilize my collapsed mind and finally, i have made it here. Thanks 🙂

Very poor example of an 'inductive' argument: inductive reasoning has its basis in frequency and experience; on observation and experiment. A ratio of 1 to 10 is a huge variation.
