Inductive learning and deductive learning

Inductive reasoning generalizes and deductive reasoning tests the generalization on a specific case. Effective learning requires both.

Similarly, tacit knowledge and explicit knowledge are essential components of an upward spiral. One prompts the other to elevate our level of knowledge. Converting explicit knowledge to tacit knowledge involves the act of internalizing what we learn. Making tacit knowledge explicit reinforces better and deeper understanding of what vaguely and fuzzily exists in our knowledge base. Not a dichotomy, but more a continuum. It's just like water exists in both the liquid and vapor form most of the time.
