Cogito Ergo SUM!

Strong induction
All observed crows are black.
Therefore:
All crows are black.
Weak induction
I always hang pictures on nails.
Therefore:
All pictures hang from nails.
The conecting of the two statements, the so called premise and conclusion, are not logical in the weak inductively reasoned statement. And you could never really conclude that all crows are black becuase you could look into the crows genes and find out that some have the possibility of becoming albino crows.

The statement by Aristotle "Contemplation is the greatest good" was inductive reasoning because he used a lifetime of his own knowledge to which he reasoned from a large number of his own particular examples to an arrived general rule. Hence the famous Quote was born. I personally think he was referring to life. All thoughout our lives we constantly "contemplate" everything... we contemplate the future the past and then present (which always seems to be just beyond our grasp). Thus i think since he calls contemplation the greatest good, and what i think he's referring to is life... then life is the greatest good.. and i agree 100% to that. This certainly leads up to "cogito ergo sum" becuase contemplation is a gift of the mind which we accomplish thanks to something im not quite aware of. Mr.Rene Descartes seems to understand that he cannot deny that he's thinking that he's thinking and so forth till infinitum.
thank you.
