However...

However, figurative happiness is not an innate and inherent aim for humans; rather, it is only called happiness by some people, that some of them think and imagine that happiness is in reaching the sensory pleasures and superintendence in worldly affairs. but the wise do know that happiness is not found in the fleeting and corrupted things.

Ibn Sina was of the opinion that intellectual pleasures cannot he compared with the sensory pleasures, but intellectual pleasures can only be comprehended and understood by those who have purified their souls from all kinds of sins and vices. Avicenna (Ibn Sina) defines (in the Esharat and Tanbihat) pleasure as comprehension of and reaching to that, which is considered as perfection and virtue for the perceptive.

He believes that the internal Pleasures, particularly the intellectual pleasures, are higher than the sensory pleasures. Avicenna says that the main reason of some people's disinterest to acquisition of rational idea is the involvement of their souls to perceptible things that debar their attention to the rational ideas, and as long as an individual does no pay attention to the rational ideas, no enthusiasm will be created for him.

He also says [in Rasael] that so some people suspect that happiness is the reaching to sensory pleasures and worldly superintendence, but the wise know that none of the sensory pleasures can be considered as happiness, because all of them are along with deficiencies and adversities. Ibn Sina admits that the real happiness is a thing that is inherently desirable and is chosen for itself, therefore, it is higher than those things which are chosen for other things.

Happiness is in the highest things that human beings are looking for, thus guiding people to happiness is considered as the highest guidance. Avicenna says in "Shafa & Najat" that the real happiness is in that man attains the perfection in speculative and practical powers.

An individual, who observes moderation in the three Powers; sensual, indignation, contrivance, and therefore obtains the Virtues of chastity, courage and wisdom, will be adorned with the virtue of justice that is the comprehensive of the three virtues, and this is the perfection of the practical power. The perfection of the speculative power is in this fact that the rational system and complete form are created in man and he transforms in to a rational world in brief.
