Chapter Eleven: The Moral Arguments
Discursive Arguments based on Moral Commands
Moral arguments have a variety of expositions. In some of its versions, the existence of an immutable and absolute authority and mentor has been argued on the basis of the immutability and absoluteness of moral codes. In some others the existence of a non-human source whose will overrules the human will has been substantiated by feeling the magnitude of moral commands in circumstances in which man’s will is tempted by other choices at his disposal. Other expositions use the mutual necessity between law and a lawgiver to prove a legislative source; or the presence of moral codes common across diverse cultures has been used to support the supposition of a god who has inscribed these codes on human hearts.
Sensing the voice of conscience or the moral command and the resultant feeling of guilt and contrition or the sense of worry and fear during or before an immoral act is the common element and shared premise of these arguments. The common weakness of all of them also stems from this premise, because only after confirmation of its accuracy is it possible - with an exposition however different from the ones mentioned - to argue for the existence of a source and cause, which it may imply. Still, this will not prove this causes’ existential and eternal necessity.
If the fundamental premise of the argument, which claims the universality of moral codes, is accepted, the argument can lead to the non-human source of these codes. In other words, if it is authenticated that every person, before acting in non-compliance with meritorious moral behavior, feels fear and unease, and afterwards, he experiences shame and regret, and the universality of these laws and rules are such that everybody - regardless of social class, race, culture, and support or ostracism from the society - undergoes the sense of sinfulness and fear, it can be inferred that the source of these codes is none of these situations, and rather they spring from a source beyond them.
The Common Criticism of the Moral Arguments
The focal point of criticism is the first premise, since there is no way to prove it. The premise could be affirmed through either induction or deduction. Induction can bring certainty only if it is complete, and we can never attain a complete induction of the consciences of all individuals. And as far as the deductive method is concerned, the relationship between the subjects and predicates of its premises, which is expressed by the copulas, must be necessary in order for the deductive method to bring certainty. Relationships are necessary when the predicate is an essential part or an essential property(al-‛aradh al-dhātī)
of the subject. In the first case, the proposition will have an analytical form, and in the latter, if it is not axiomatic, it must be made so by using axiomatic middle terms.
The universality of moral commands in a way that they are acknowledged by everyone is disputable. In order to adequately justify the existence of God on the grounds of the universality of moral commands, the argument must first prove the said premise in an ascertaining manner, since in philosophic matters, nothing less than certitude is satisfactory.
Because disciplines, which are dedicated to the inquiry of natural phenomena are meant to advance practical purposes, they can make due with conjectural information also. Rather, in many instances, because of the difficulty of attaining certitude, the natural scientist does not have a choice but to suffice on uncertain hypotheses.
A science dependent on experiment and induction, such as medicine, cannot abandon patients struggling between life and death and wait for the attainment of certitude. Rather, it is forced to try to solve the imperative issues of life by making use of theories with an acceptable probability of success.
While mathematical sciences depend upon natural premises, or are used with regard to natural phenomena, they also face the dilemmas faced in the natural sciences, and consequently, lose their syllogistic quality.
Should the existence of surface, which is used in most geometric figures, be doubted on the basis of theories such as the atomic theory of Democritus, it will entail uncertainty about the natural and external existence of any figure that an architect may draw for a building. Nevertheless, the architect - despite his doubts, but with a decent probability of the validity of his view, or even without regard to its validity or invalidity - uses the sketch because of the confidence he has in its practical applications.
Cognition of God as a reality, which is the foundation of faith and bastion of true belief can neither be based on hypotheses that have solely practical use and lack ontological veridicality, nor can it be founded upon conjectural information. This is because conjecture has no use in a field where the criterion is certitude, and where the claimants are not satisfied with anything less than certitude. “Verily conjecture availeth not the truth at all.”
“Say [O’ Our apostle Muhammad], ‘Bring forth your proof if ye be truthful.’”
The validity of the moral arguments depends on proving the minor premise. And until it is proved, the argument remains subject to doubt, since doubt does not depend on disproving the claim; the inability to prove the claim is enough to cast doubt. In addition to that, since the said premise is in the form of universal affirmative, it cannot be proved by presenting particular examples.
If, as is actually the case, the arguer holds that the immutable and universal moral commands are not brought about by any particular cultural, political, economical, or psychological condition, given it is a universal and all-encompassing assertion, its truth must be proved for every situation; and until it is proved, its universality remains subject to skepticism. Rather, the discovery of even one example contradicting the held universal affirmative is sufficient to explicitly illustrate its falsehood. Moreover, if in the absence of one of these conditions, even if one individual dismisses these moral commands, the influence of that absent condition in the formation of moral commands can be inferred. For these reasons and the ones to come, the affirmation of the Necessary as the only authority who is the source and cause of moral principles, on the basis of moral commands, is questionable.
The Affirmation of Incorporeal Existence through Analysis of Reason
Through analysis of the activities of both practical and theoretical reasons, Islamic philosophers have argued for metaphysical and supernatural existence. However, their approach is different from the moral arguments above, where God’s existence has been used to explain the prevalence of universal moral codes shared across different social and natural conditions.
In the fourth chapter of Al-Ishārāt wa al-Tanbihāt, Ibn Sīnā, may God bless his tomb, conducts an exceptional analysis of the psyche. On the grounds that the activities of the theoretical reason(al-‛aql al-nadharī)
and other inner conditions such as love, sincerity, will, and the like, are not marked by any physical and material characteristics, he argues for the incorporeality of soul.
Ibn Sīnā’s argument can unquestionably proceed even from a single universal concept, will, or sincerity of a single human being, in a specific condition. However, this argument does not prove the Necessary. It merely proves incorporeal existence; and even the incorporeal being, which it proves is not outside or beyond the soul. Its conclusion is limited to the incorporeality of the soul and some of its theoretical and practical features.
Kant’s Moral Arguments
Emmanuel Kant does not intend to theoretically analyze moral commands and explain them on theistic accounts; rather, he holds that the acknowledgement of moral commands presupposes the existence of God, the everlastingness of soul, and some other issues that he views the theoretical reason(al-‛aql al-nadharī)
incapable of discerning. He believes that after the practical reason(al-‛aql al-‛amalī)
discerns moral commands, which are necessarily true, the mind inevitably acknowledges their corollary, namely the existence of God and the everlastingness of the human soul. Therefore, from Kant’s perspective, faith in God is founded on moral consciousness as opposed to the moral codes being based upon belief in God.
Notice that Kant’s argument from the truth of moral commands, which are aimed to promote summum bonum, that is, the highest good, to the external existence of the highest good and everlastingness of the soul does not rely on the induction of moral commands in every human being. Moreover, it does not endeavor to trace the presence of these principles to their source. And finally, it only depends on the discernment of these commands by people who can discern them. Notwithstanding, his argument is open to two fundamental criticisms. These criticisms undermine the tenability of his argument even if one does not dispute Kant’s position that the practical reason(al-‛aql al-‛amalī)
acknowledges these commands.
The First Criticism of Kant’s Moral Argument
The first criticism states that Kant’s argument cannot indicate the existence of the Necessary, soul, free will, and so forth, since in Kant’s view, if mental concepts are not associated with sensual perception, they cannot narrate about the external world or bear any meaning with respect to reality. Therefore, the mutual necessity he suggested between principles of the practical reason(al-‛aql al-‛amalī)
and the acknowledgement of God and human will and so on, has only moral value, and does not open a window to the external world.
Kant’s moral argument does not demonstrate God’s existence as an external reality, nor does it satisfy any doubts a person may have about God. It merely says that if one wants to think morally, he must embrace these presuppositions. In other words, if the moral principles, which are embedded in the practical reason, are acknowledged, the existence of will, free choice, soul, everlastingness thereof, and the existence of the highest good must be acknowledged as well. One need not be reminded that such acknowledgement, as far as the narration of reality is concerned, is devoid of any credibility. Therefore, his moral argument does not prove the existence of God, a reality Who calls forth the ascent of humans towards Himself as claimed by the Divine religion.
The Second Criticism of Kant’s Moral Argument
The second criticism questions whether any moral command can yield knowledge of a proposition, such as the existence of God or the everlastingness of human soul, which is pertinent to the theoretical reason. Moral commands pertain to the theoretical reason(al-‛aql al-nadharī)
and have specific subjects and predicates, and some of these propositions, as stated by Kant, are self-evident to the practical reason(al-‛aql al-‛amalī)
. However, regardless of which propositions are self-evident, a proposition, which belongs to the theoretical reason(al-‛aql al-nadharī)
, cannot be reasonably deduced from propositions, which pertain to the practical reason. Therefore, moral commands do not lead to theoretical propositions. This is not to deny that new propositions pertinent to the practical reason(al-‛aql al-‛amalī)
can be inferred from syllogistic arrangement of propositions pertinent to the practical reason with propositions pertinent to the theoretical reason. That is, when a principle of the practical reason is added as a major premise to a proposition pertinent to the theoretical reason, this addition forms a syllogism the conclusion of which - in terms of being affirmative or negative, universal or particular, and likewise in being theoretical or practical - like all syllogisms, is determined by its inferior premise. And since in this sort of syllogism the major premise is a practical proposition, the conclusion will be a practical proposition as well. For instance:
A teacher educates a pupil.
Anyone who educates someone else deserves his respect.
Therefore, the teacher deserves to be respected by the pupil.
In the example above, the first proposition narrates an external reality. The second proposition is related to the practical reason(al-‛aql al-‛amalī)
, and the syllogism’s conclusion is a practical and moral principle.
Practical principles, before reaching the stage of implementation, and before appearing before human will and choice in the form of a particular duty, inevitably depend upon particular and specific theoretical premises, which relate to external individuals and realities. Therefore, in order to be applicable, moral commands make use of some theoretical and ontological propositions that convey the existence of numerous particular realities, like the propositions “The highest good exists,” “A being with free will is real,” and “The needy and the free of need exist in the external world.” Hence, if the highest good does not exist, the moral command “One must endeavor to reach the highest good” can never come into effect and can never oblige anyone to do anything. Similarly, if free will does not exist, none of the moral propositions can be applicable. Likewise, if there are no needy, no duty can confront those free of need.
To conclude, none of the presuppositions of the practical reason(al-‛aql al-‛amalī)
can prove the realities that bring about the existence of their subjects or accommodate the conditions of their coming into effect. Doubts about free will or the existence of the highest good, concepts included in moral commands, cannot be effaced by relying on moral commands themselves. Instead, it is the discursive affirmation of these realities that lends credence to moral commands. Similarly, the said concepts satisfy the necessary condition of the abstraction of self-evident concepts and formulation of self-evident moral commands. In other words, the mind, through conception of goodness, the highest good, its short-comings, and the free will it has, conceives the moral obligation of trying to obtain that conceived good and then decides to procure it. Therefore, contrary to what Kant presumes, despite the mutual necessity, which exists between the truth of moral commands and some theoretical propositions, the necessity does not spring from moral commands; rather, theoretical premises necessitate moral propositions. In short, certain theoretical concepts and judgments about man and the world necessitate the fundamental moral commands.
If the naturalistic perspective were valid - that is, as the verse of the Noble Qur’ān narrates the position of the sensualist people, “There is nothing but our life in this world; we die and we live and we shall not be raised again,”
should human life be restricted to this world and should the human soul not be everlasting, or the human soul, as in Kant’s philosophy, be doubted, or God as the highest good, the one Who is desired by virtue of His Essence(al-matlūb bi al-dhāt)
be a mere concept without any external extension - though when the practical reason(al-‛aql al-‛amalī)
conceives the subjects and predicates of the moral propositions, it may acknowledge their validity, however, one is justified in wondering what relevance such moral commands have. In a world where there is no God, no absolute virtue, and the human being is a mere body, moral commands cannot oblige anyone to do anything, and thus, they cannot call forth sacrifice as a moral obligation, when vanity tempts the soul towards other considerations.
