Why do people respond to commands?

Why do people obey to commands? Because they are immediately inclined, in a behaviourist way, to obey? Or because they realise that the action commanded is an instrument to the realisation of a coveted goal? Or are there further explanations?

This question has been debated at length in Sanskrit philosophy, oscillating especially among three main positions. I discussed these positions with some accuracy in previous posts, but this time I would like to try a bird-eye view about what is at stake.

On the one side, Maṇḍana claimed that the only motivator for undertaking actions is the awareness of the fact that the action to be undertaken is the means to obtain a desired goal. On the other, Prabhākara’s followers claimed that we immediately obey to commands because we feel enjoined, and only later analyse what is being asked and why. The role of the mention of the listener’s desire in commands such as “If you want to lose weight, try this shake!” is not meant to say that the enjoined action is an instrument to realise the desired output. Rather, the mention of the desire is meant for the listener to understand that they are the person addressed by the prescription. It picks up the person, who immediately relates with their own desires, but does not describe the existence of an instrumental relation between enjoined action and result. The last position can be connected to Bhartṛhari’s pratibhā theory. As depicted by Maṇḍana, this is a general theory about meaning, which includes both commands and descriptive sentence. According to it, human as well as non-human animals have innate inclinations which make it possible for them to perform activities they could have never learnt but are still able to perform, such as swimming or breastfeeding in the case of a baby. The pratibhā theory can be extended to commands which one would respond to because of an innate inclination.

Maṇḍana’s theory has the clear advantage of being a reductionist theory. By following it, one does no longer need an ad hoc semantic theory for commands, which can be reduced to descriptive sentences explaining the relation between the action enjoined and the expected output. Similarly, Maṇḍana provides a single theory covering all aspects of motivation to act, both in the case of commands and in the case of autonomous undertakings of action. In all cases, one is motivated to act because one thinks that the action is the instrument to get to the expected result. What are the disadvantages of this theory? First of all, Prābhākaras have a point when they describe our first response to commands. We immediately feel enjoined even before starting to analyse the action we have been required to perform. Secondly, Maṇḍana’s theory might have problems when it comes to people who know what would be best for them, but still don’t act. Can this all be explained just in terms of desires and instruments?

As declared at the beginning, the above is my attempt to give a short overview of the debate. Comments are welcome!

Maṇḍana’s intellectual theory of motivation

Maṇḍana’s thesis is an answer to the problem of how to identify the core of a prescription. What makes people undertake actions? Kumārila’s śabdabhāvanā theory and Prabhākara’s kāryavāda had already offered their answers. Maṇḍana expands on Kumārila’s intuition about human behaviour being always goal-oriented by offering a radical reductionist hypothesis. According to this hypothesis, being a motivator is nothing but communicating that the action to be undertaken is an instrument to some coveted result. In this sense, prescribing X to people desiring Y is nothing but explaining that X is the means to achieve Y.

This cognitive interpretation of what motivates one to act could be accused of intellectualism. What about agents who, though understanding that X would be the appropriate course of action, do not undertake it, perhaps out of sloth?

A possible answer is that Maṇḍana’s theory describes the behaviour of ideal agents, who are able to evaluate rationally what is the best means to a coveted goal. Alternatively, one might suggest (as hinted at at the end of section 11.2) that even such irrational people would be impelled to act, even if they then do not physically undertake any act. The iṣṭasādhanatā is a motivator even for them, although they do not act correspondingly. One might think of the comparable case of someone who intensely desires an ice-cream and comes to know that great ice-creams are available in a given part of the city. They are ready to go there, but undergo an accident and are prevented from going. Although they do not practically act, the knowledge about the ice-cream shop did act as motivator for them.

Correspondingly, pravṛtti is used as a synonym of prayatna `effort’ and indicates the undertaking of an activity, not yet its realisation. Similarly, a person said to be pravṛtta is one who has already conceived the decision to undertake an action, although no movement can be seen yet.

A preliminary understanding of pratibhā

Within chapter 11 of his masterpiece, the Vidhiviveka `Discernment about prescription’, Maṇḍana identifies the core element which causes people to undertake actions. Maṇḍana expands on Kumārila’s intuition about human behaviour being always goal-oriented by offering a radical reductionist hypothesis. According to this hypothesis, being a motivator is nothing but communicating that the action to be undertaken is an instrument to some coveted result. In this sense, prescribing X to people desiring Y is nothing but explaining that X is the means to achieve Y.

At this point, Maṇḍana introduces some opponents, mainly one upholding pratibhā.

The term pratibhā is found in Bhartṛhari, whom Maṇḍana extensively quotes in chapter 11 of his Vidhiviveka. It is clear that Maṇḍana suggests the pratibhā as an alternative way of making sense of what motivates people to act. In this sense, pratibhā is a pravartaka `motivator’, something causing one to act. It is the key alternative to Maṇḍana’s own proposal that the knowledge that the enjoined action will lead to a desired result is what causes people to act. The pratibhā theory radically opposes this one.

In fact, Maṇḍana’s theory is primarily cognitive (you act with regard to X because you know something relevant about X), whereas the pratibhā theory is almost behaviourist (you act with regard to X because of the pratibhā inducing you to act).

The Prābhākara opponent within Maṇḍana will later appropriate this theory and join it with their own deontological understanding, according to which we act primarily because we are enjoined to do so, thus adding a deontological nuance which was absent in Bhartṛhari’s view of pratibhā.

But what is pratibhā before its Prābhākara reinterpretation? A key passage for the understanding of the pratibhā theory in Maṇḍana before its Prābhākara appropriation is the very sentence introducing it, at the beginning of section 11.3. There, the opponent suggests pratibhā as the thing causing one to undertake an action. An uttarapakṣin asks which kind of artha this is and the answer is at first sight surprising: It is no artha at all (na kaścit). What is it then? It is a cognitive event (prajñā) leading to action.

The point seems to be that there is no mental content, but only the urge towards acting. The pratibhā is a mental state without intentional content.

A further hint is found at the beginning of 11.5, where Maṇḍana responds to the paradox that the pratibhā cognition has no object, but it causes activity. This results, says Maṇḍana, in an undesirable consequence. In fact, if in the case of pratibhā the cognition of the connection between word and meaning plays no role, because the pratibhā has no intentional content, a person hearing a prescription should act independently of any cognition of the meaning.

But can we have purely agentive mental states? Can there be incitement to action without any content?

I am grateful to Hugo David for an inspiring talk on pratibhā back in 2018. This interpretation should, however, not be blamed on him. Similarly, I am always grateful to Elliot Stern for his edition of the Vidhiviveka and for the work we shared in the last 12 months.
