Thinking about 'Thoughts without a Thinker'

 That is, while science is quite capable of discussing the world without a maker, it is still searching for appropriate ways of discussing thoughts without a thinker. Fortunately, Indian Buddhist analyses of mind are already expressed in a philosophical language which avoids the postulation of experiential subjects without diminishing the importance of the experiential dimension—a language which therefore provides rich opportunities for dialogue with scientific approaches to understanding mind. This is possible because there is a growing consensus in Western thought and science that we may understand ourselves and our world more deeply if we think in terms of patterns of relationships rather than of reified essences or entities—if we think, in short, in terms of dependent arising.
Whatever exists comes about dependent upon its enabling conditions and persists as long as such conditions persist..."what complex of conditions operates in what recurrently patterned ways in order to typically give rise to what kind of phenomena?" But this focuses our attention upon patterns of arising rather than on actions of agents; and patterns are relational, not substantive, and arising is dynamic, not static.5 The Buddhist dismissal of selves, essences or unchanging entities, therefore, does not arise from logical propositions derived from first principles, such as 'all is change,' as much as it follows from the form of the question being raised, "how do things come to be?" —a point which is all the more obvious by a similar disavowal of essences, entities or substantive selves in modern science.
Many, if not most, scientific works on brain and consciousness reject the notion of a "unified, freely acting agent." For example, brain scientist Richard Restak (1994, pp. 120-121) argues: "Brain research on consciousness carried out over the past two decades casts important doubts on our traditional ideas about the unity and indissolubility of our mental lives," particularly "the concept of ourself as a unified, freely acting agent directing our behavior." Lakoff and Johnson (1999, p. 268): "The very way that we normally conceptualize our inner lives is inconsistent with what we know scientifically about the nature of mind. In our system for conceptualizing our inner lives, there is always a Subject that is the locus of reason and that metaphorically has an existence independent of the body. As we have seen, this contradicts the fundamental findings of cognitive science." 


The mind is inherently embodied.

Thought is mostly unconscious.

Abstract concepts are largely metaphorical.

Reason is not completely conscious, but mostly unconscious.
Reason is not purely literal, but largely metaphorical and imaginative.
Reason is not dispassionate, but emotionally engaged.

Reason is not disembodied, as the tradition has largely held, but arises from the nature of our brains, bodies, and bodily experience. This is not just the innocuous and obvious claim that we need a body to reason; rather, it is the striking claim that the very structure of reason itself comes from the details of our embodiment. The same neural and cognitive mechanisms that allow us to perceive and move around also create our conceptual systems and modes of reason. Thus, to understand reason we must understand the details of our visual system, our motor system, and the general mechanisms of neural binding. In summary, reason is not, in any way, a transcendent feature of the universe or of disembodied mind. Instead, it is shaped crucially by the peculiarities of our human bodies, by the remarkable details of the neural structure of our brains, and by the specifics of our everyday functioning in the world.
For example, there is no Cartesian dualistic person, with a mind separate from and independent of the body, sharing exactly the same disembodied transcendent reason with everyone else, and capable of knowing everything about his or her mind simply by self-reflection. Rather, the mind is inherently embodied, reason is shaped by the body, and since most thought is unconscious, the mind cannot be known simply by self-reflection. Empirical study is necessary.
There exists no Kantian radically autonomous person, with absolute freedom and a transcendent reason that correctly dictates what is and isn't moral. Reason, arising from the body, doesn't transcend the body. What universal aspects of reason there are arise from the commonalities of our bodies and brains and the environments we inhabit. The existence of these universals does not imply that reason transcends the body. Moreover, since conceptual systems vary significantly, reason is not entirely universal.
Since reason is shaped by the body, it is not radically free, because the possible human conceptual systems and the possible forms of reason are limited. In addition, once we have learned a conceptual system, it is neurally instantiated in our brains and we are not free to think just anything. Hence, we have no absolute freedom in Kant's sense, no full autonomy. There is no a priori, purely philosophical basis for a universal concept of morality and no transcendent, universal pure reason that could give rise to universal moral laws.

       The utilitarian person, for whom rationality is economic rationality--the maximization of utility--does not exist. Real human beings are not, for the most part, in conscious control of--or even consciously aware of--their reasoning. Most of their reason, besides, is based on various kinds of prototypes, framings, and metaphors. People seldom engage in a form of economic reason that could maximize utility.
...The grounding of our conceptual systems in shared embodiment and bodily experience creates a largely centered self, but not a monolithic self....Because our conceptual systems grow out of our bodies, meaning is grounded in and through our bodies. Because a vast range of our concepts are metaphorical, meaning is not entirely literal and the classical correspondence theory of truth is false. The correspondence theory holds that statements are true or false objectively, depending on how they map directly onto the world--independent of any human understanding of either the statement or the world. On the contrary, truth is mediated by embodied understanding and imagination. That does not mean that truth is purely subjective or that there is no stable truth. Rather, our common embodiment allows for common, stable truths.

If we are going to ask philosophical questions, we have to remember that we are human. As human beings, we have no special access to any form of purely objective or transcendent reason. We must necessarily use common human cognitive and neural mechanisms. 

In asking philosophical questions, we use a reason shaped by the body, a cognitive unconscious to which we have no direct access, and metaphorical thought of which we are largely unaware. The fact that abstract thought is mostly metaphorical means that answers to philosophical questions have always been, and always will be, mostly metaphorical. In itself, that is neither good nor bad. It is simply a fact about the capacities of the human mind. But it has major consequences for every aspect of philosophy. Metaphorical thought is the principal tool that makes philosophical insight possible and that constrains the forms that philosophy can take.

Philosophical reflection, uninformed by cognitive science, did not discover, establish, and investigate the details of the fundamental aspects of mind we will be discussing. Some insightful philosophers did notice some of these phenomena, but lacked the empirical methodology to establish the validity of these results and to study them in fine detail. Without empirical confirmation, these facts about the mind did not find their way into the philosophical mainstream.
