Elements of Mind (EM) has two themes, one major and one minor. The major theme is intentionality, the mind’s direction upon its objects; the other is the mind–body problem. I treat these themes separately: chapters 1, and 3–5 are concerned with intentionality, while chapter 2 is about the mind–body problem. In this summary I will first describe my view of the mind–body problem, and then describe the book’s main theme. Like many philosophers, I see the mind–body problem as containing two sub–problems: the problem of mental causation and the problem of consciousness. I see these problems forming the two horns of a dilemma. Just as the problem of mental causation pushes us towards physicalism, so the problem of consciousness pushes us away from it. Each problem reveals the inadequacy of the solution to the other. Essentially the problem of mental causation is the conflict between (i) the apparent fact that mental states and events have effects in the physical world and (ii) a general principle about the causal nature of the physical world, which is sometimes called the ‘causal closure’ or the ‘causal completeness’ of the physical world. This principle says that all physical effects have physical causes which are enough to bring them about. The problem then is simple: how can a mental cause have a physical effect if that effect also has a physical cause which is enough to bring it about? Barring massive overdetermination of our actions by independent causes, it seems that the best answer is to identify the mental and the physical causes. And this is traditionally how physicalists have argued for their identity theory of mind and body. However, many physicalists reject the identity theory, and therefore they have to solve the mental causation problem in some other way. At present, there is no consensus among physicalists on which of the currently proposed solutions is correct. In chapter 2 of EM I propose an alternative, which I call ‘emergentism’. Inspired by the rejection of the identity theory, Emergentism is the idea that mental properties are genu..

This groundbreaking book is about Karl Popper's early writings before he began his career as a philosopher. The purpose of the book is to demonstrate that Popper's philosophy of science, with its emphasis on the method of trial and error, is largely based on the psychology of Otto Selz, whose theory of problem solving and scientific discovery laid the foundation for much of contemporary cognitive psychology. By arguing that Popper's famous defense of the method of falsification as well as his elaboration of an evolutionary theory of knowledge are equally indebted to German psychology, Michel ter Hark challenges the received view of the development of Popper's philosophy. He concludes the book with a reinterpretation of Popper's theory of the mind-body problem, emphasizing its contemporary relevance.

In this paper Popper formulates and discusses a new aspect of the theory of mind. This theory is partly based on his earlier developed interactionistic theory. It takes as its point of departure the observation that mind and physical forces have several properties in common, at least the following six: both are (i) located, (ii) unextended, (iii) incorporeal, (iv) capable of acting on bodies, (v) dependent upon body, (vi) capable of being influenced by bodies. Other properties such as intensity and extension in time may be added. It is argued that a fuller understanding of the nature of forces is essential for the analysis of the mind-brain problem. The relative autonomy and indeterministic nature of mind is stressed. Indeterminism is treated in relation to a theorem of Hadamard. The computer theory of mind and the Turing test are criticized. Finally the evolution of mind is discussed.

The mind-body problem concerns the relationship between mind and body, or nowadays - between mind or consciousness and the brain. As a relationship, this can be viewed from two perspectives: from body to mind and from mind to body. In this note I point out that the two readings of the problem are not symmetrical and that there are categorical differences between them. In particular, whereas the body to mind problem constitutes a mystery (cf. the contemporary hard problem), the mind to body problem may be approached from a psychological (as contrasted with philosophical) orientation that allows for concrete phenomenological investigation.

The mind-body problem is the problem of explaining how our mental states, events and processes—like beliefs, actions and thinking—are related to the physical states, events and processes in our bodies. A question of the form, ‘how is A related to B?’ does not by itself pose a philosophical problem. To pose such a problem, there has to be something about A and B which makes the relation between them seem problematic. Many features of mind and body have been cited as responsible for our sense of the problem. Here I will concentrate on two: the fact that mind and body seem to interact causally, and the distinctive features of consciousness. A long tradition in philosophy has held, with René Descartes, that the mind must be a non-bodily entity: a soul or mental substance. This thesis is called ‘substance dualism’ (or ‘Cartesian dualism’) because it says that there are two kinds of substance in the world, mental and physical or material. One reason for believing this is the belief that the soul, unlike the body, is immortal. Another reason for believing it is that we have free will, and this seems to require that the mind is a non-physical thing, since all physical things are subject to the laws of nature. To say that the mind (or soul) is a mental substance is not to say that the mind is made up of some non-physical kind of stuff or material. The use of the term ‘substance’ is rather the traditional philosophical use: a substance is an entity which has properties and persists through change in its properties. A tiger, for instance, is a substance, whereas a hurricane is not. To say that there are mental substances— individual minds or souls—is to say that there are objects which are non-material or non-physical, and these objects can exist independently of physical objects, like a person’s body. These objects, if they exist, are not made of non-physical ‘stuff’: they are not made of ‘stuff’ at all..

The Cartesian distinction between res extensa and res cogitans initiated in the early modern age the philosophical discourse with regard to an adequate explanation of the nexus between the body and the mind. The causal closure of the body (as essentially a physical phenomenon) seems to exclude both the physical and neuronal causation of mental states and operations as well as the mental causation of bodily states and processes. The following treatise is an attempt to re-examine the causal connectivity between the body and the mind and thereby to explain the mysterious interaction between these two entirely distinct modes of existence and reality. The neuronal causation of the mental existence of human beings, and conversely the mental causation of bodily volition seem to surpass the framework of ordinary causal processes which are primarily conceived as temporal sequences of causes and effects in natural phenomena. The existence of the conscious subject – as res cogitans – can hardly be reduced to momentary neuronal processes of causation; it implies a constant ontological causation in which the elementary physical and material modes of being cause constantly and ontologically the mental states and operations – which eventually form higher and unitary modes of being. This dual nature of a neuronal-ontological causation, namely the constant and existential causation of the mind and the momentary causation of mental processes (sensation, perception, cognition, thinking, etc.), seems to resolve the problem of the causal connectivity between the body and the mind. However, the ontological causation cannot be restricted to the causal interaction between the body and the mind; it can be extended to the modes of existence of the overall physical i. e. material reality.

* Argument from authoritative self-knowledge ("privileged access" to one's own mental states) 1. We have a "privileged access" to our own mental states in the sense we have the authority on what mental states we are in. 2. Through introspection, we are aware of our mental states but not aware of them as physical states of any sort or as functional states. 3. Therefore, our mental states cannot be physical states.
