What is the relationship between inductive to deductive reasoning?

Deductive reasoning makes things smaller. It goes from the general to the specific. If I know that gravity affects all things, and I have a thing, then I know that my thing will be affected by gravity.

Inductive reasoning does exactly the opposite - it tries to come up with general rules from specific examples. If everything I've ever encountered is affected by gravity, then it seems reasonable to assume that all things are affected by gravity.

Both forms of reasoning are prone to error, of course (for all we know, there may be something in the universe immune to gravity). And they are, to an extent, reliant upon each other. Where will you ever get general rules to deduce with except from induction? What is the point of induction unless you are going to deduce with its conclusions?

As to why humans organize... this is essentially what learning IS. You filter the relevant out from the irrelevant, observe patterns and extend them to novel phenomenon. And because learning is such a powerful tool, even creatures with far less brains than we have do it naturally. It is a matter of survival... perhaps the best survival tool there is!

Deductive you get DIRECTLY from the facts WITHOUT any outside information. I will DEDUCE line #3 from ONLY the information found in lines #1 and #2 as follows:

1.) I have a red shirt
2.) All red things are pretty

3.) My shirt is pretty

Inductive you get from INDIRECT reasoning...I can INDUCE that i will get fired if i make a habit of being late and missing work...even if there is NO explicit rule or information about the connection between my tardiness and my termination...

because of the fact human beings desire to check from their errors as rapidly as feasible. how many circumstances does it take working into closed doorways till now you generalize the belief of beginning all doorways till now attempting to bypass by using them?
