Sure, Induction is the basis of knowledge. But, it can’t tell you why something is the way it seems to be. And, it also can’t tell you if it will always be that way. For that you need theories and models that can be repeatedly tested.
For example, if you wake up every day and see the sun rise, it’s safe to assume that it will always rise. But, without understanding the forces that cause the sun to rise (and the forces that cause those forces), you can’t really be sure. And, even then, an unaccounted and unknown force can come along and break the model (see: the black swan problem).
Induction is unavoidable and very important, but it also the root of many logical errors. In social science, there are so many unknown forces at work, theories are very fragile.
