Philosophy (from Greek φιλοσοφία, philosophia, literally "love of wisdom") 

To Humans it was given and 
it is its nature.
with its consideration,
All things to messure.

The eyes can not see the
distance of a place,
But in truth,the mind of Humans,
Narrows the space.

The elements of Time,
of rest have none,
In good and bad,
they walk and run.

(Mantinades/poetry of philosophy from Erotokritos)
