Inductive reasoning or deductive reasoning?

There are two ways that we come to have knowledge. One is by reasoning from repeated observations (inductive), the other is by ensuring the conclusion follows validly from the premises (deductive). 

The two are inextricably linked. Each makes an argument that helps advance our knowledge of the world.

More surprisingly, each argument fails by the standards of the other!

Inductive vs deductive reasoning

Inductive reasoning is about coming to a conclusion from specific instances (empirical data), deductive reasoning is about coming to a conclusion from premises (logical reasoning).
