In addition, each of them has its percentage, etc. Sometimes the cause is seemingly found, but this does not get us nearer the solution. For example, let ...

Inquiry
An inquiry is any process that has the aim of augmenting knowledge, resolving doubt, or solving a problem. A theory of inquiry is an account of the various types of inquiry and a treatment of the ways that each type of inquiry achieves its aim.
