If an object is composed of several parts...
If an object is composed of several parts, such as a building, until all the parts are put together, it is said that the object is deficient and incomplete and when all the parts have been assembled, it is said that the object is complete. However, perfection applies to levels and stages.
For instance, a new born child, although healthy and complete with all the natural parts and organs, is in one respect deficient and must pass through the various levels of perfection by means of training and education in order to attain to perfection. In other words, tamam is used where all the necessary parts for composing a whole are present, otherwise that whole is deficient in its essence.
On the other hand, kamal is used when an object has reached completion but has the capacity to improve and acquire higher degrees. Thus, an object could be complete but not perfect. But as to the difference of kamal (perfection) from pishraft (progress), it can be said that the idea of elevation is embedded in the meaning of perfection. Perfection is a movement but a vertical one, from lower degrees to higher and loftier degrees, unlike progress which can also apply to a horizontal movement.
For instance, if an army is at war and is conquering enemy territory and moving ahead, it is said that the army is progressing, not perfecting. Therefore, social perfection denotes human elevation in the social context not merely progress, for there are many changes that might be considered as progress for the human being or the society but might not necessarily indicate perfection or elevation. Human Perfection from the Point of View of Islam 1.
Perfection Dependent on Vision and Acquisition One must endeavour to fully understand the Divine sciences and conduct himself accordingly. That is, he must put his knowledge into action. Just as virtues are interrelated with perfect and complete acts of worship, vices are interrelated with deficient and ineffective acts of worship. 2.
Perfection Contingent on Sensing Danger He who knows that something dangerous is threatening him and might result in his being left hungry and thirsty in the middle of nowhere will embark on solving the dangerous situation. The person who constantly reminds himself of the hardships of the hereafter and the chastisement of hell, realizing the danger, will struggle to attain to perfection and avoid all deficiencies.
For unless one feels the deficiency and insufficiency of his state, he will not advance toward perfection.
