The pleasure which is obtained through it is a perfection...
The pleasure which is obtained through it is a perfection for the faculty which perceives it, and it is common between man and animals. Moreover, if the eating of food is for a righteous intention, and in order to obtain power for the performance of one’s divine duty, this will bring about a human perfection. In this case it will be a means of obtaining real goodness, as well.
However, if it is merely for animal pleasure, especially if prohibited foods are used, this will merely cause the perfection of some of a person’s faculties, and will do harm to his ultimate perfection. In conclusion, it will not yield the real perfection of man.
Hence, it is called ‘fancied goodness’ or ‘imagined goodness.’ Furthermore, the situations appropriate to the use of the expressions ‘freedom’ ( ikhtiyār ) and ‘goodness’ ( khayr ) have also become clear, for every voluntary agent performs only those deeds which are appropriate to his own perfection, and among the voluntary agents, intentional agents perform deeds which are means for achieving their own perfection and good, whether real or fancied, even if the supposed good is pleasure or escaping from pain and suffering.
It is possible that difficulties may be raised regarding the universality of this principle, for there may be people who are uninterested in worldly pleasures who at least perform some voluntary deeds for the good of others and pay no heed to their own good, and sometimes they even sacrifice their own lives for others. So it cannot be said that generally, every intentional agent performs his deeds for his own good and to reach perfection!.
The answer is that these sorts of deeds, whether they are performed due to the influence of the arousing of emotions, or for the sake of achieving an eternal reward or the pleasure of God, ultimately lead to the good of the agent himself; that is, as a result of such self-sacrifice, he either satisfies his emotions, or he attains to spiritual and heavenly stations and divine pleasure.
So, the fundamental motivation of the agent is the attainment of his own perfection and goodness, and service to others is really a means for obtaining perfection. At the utmost sometimes man’s motivations are effective in a conscious form, sometimes semi-consciously, and sometimes unconsciously.
