Diseases
Some say that we owe our consciousness to our hearts and that it is the heart which suffers pain and feels anxiety order strattera 10 mg online medications in carry on. But this is not the case; rather order strattera 18 mg fast delivery medications going generic in 2016, it is torn just like the diaphragm order strattera 10 mg fast delivery treatment authorization request, and even more than that for the same reasons: for blood vessels from all parts of the body run to the heart, and it encapsulates these, so that it can feel if any pain or tension occurs in a human being. Moreover, it is necessary for the body to shudder and to contract when it feels pain, and when it is overwhelmed by joy it experiences the same. Yet neither of these parts has any share in consciousness; rather, it is the brain which is responsible for all these. Heart, brain, blood, pneuma 127 This passage is part of a rather complicated explanation of epilepsy (for details on this see the next paragraph). The brain plays a pivotal role in this explanation as it is the point from where bodily and psychic faculties are co-ordinated, but also because it is particularly sensitive to harmful influences from the environment, such as climate and season (‘so long as it is healthy’). These influences can therefore be additional factors that contribute to the course the disease takes. The author emphasises this crucial role of the brain as part of his polemic against two rival factions which consider the diaphragm or the heart to be the central organ that is the source of consciousness. He dismisses the etymological argument of the first faction (phrenes – phronesis¯ ) as invalid, and accommodates the empirical fact that both factions put forward – the heart’s leaping in case of sudden gladness or sadness – into his own theory, which is also based on empirical observations (namely the delicacy of the diaphragm and the veins going to the heart). In a previous chapter he employed an empirical argument to support his conviction that the disease is caused by an accumulation of phlegm in or around the brain. He claimed that if one were to open the skull of a goat that died as a result of an epileptic fit, one would find a large amount of fluid (phlegm) around the brain. In this context phronesis¯ clearly means more than ‘thinking’ or ‘intelligence’, as the word is commonly translated. It means ‘having one’s senses together’ and refers to a universal force by which a living being can focus on its surroundings and can un- dertake activities; it also implies perception and movement. Another thing that is striking is that the author is of the opinion that the brain is also the source of feeling – although he admits that the heart and diaphragm take part in this as well. A text in which mental phenomena are even more clearly classified as a separate category is the Hippocratic writing On Regimen. As to the question whether this indeed concerns an experiment in the modern sense of the word, see Lloyd (1979) 23–4. There is a dispute about the date of this work: most scholars date it to the beginning of the fourth century bce, but some argue in favour of a much later date (second half of the fourth century bce). The soul consists of wa- ter and fire (the elements which, according to this author, have the greatest influence on the constitution of the human body), which stand in a certain proportion to each other. Fluctuations in this proportion result in differ- ences between individual people’s cognitive skills, such as acuteness, a good memory, precision of the senses and proneness to certain emotions (1. When the balance between these two elements is seriously disturbed, it will give rise to psychological disorders, but these can be cured by changing eat- ing and drinking habits and adopting a certain lifestyle (1. According to this author, the soul is therefore a material entity, yet it does not have a fixed location: it moves through the body via ‘passages’ (poroi ). The condition of these passages (for instance their width or narrowness) is a further influential factor in someone’s mental functioning. In the state of wakefulness, the soul distributes itself over the entire body and carries out certain tasks ‘for the benefit of the body’, including hearing, seeing, touching and movement. During sleep, or rather ‘when the body is asleep’, the soul remains awake and withdraws in its own ‘home’ (oikos), where it carries out the activities of the body independently. These include seeing, hearing, walking, touching, grieving, thinking: they are called enhupnia or ‘dreams’. Yet the author does not venture an opinion on the location of the soul and its ‘home’. A presentation like this shows how inadequate terms like ‘materialism’ and ‘dualism’ are to describe ancient theories on body and mind. The author of On Regimen may be called a materialist to the extent that he holds an entirely material view on the soul; yet at the same time he assumes two separate entities which may normally co-operate and mutually influence each other, yet one of them (the ‘soul’) can also function independently, as, for instance, in sleep. He expresses the view that the ‘soul’ is not a separate entity, which might exist independently of the body: ‘soul’ to Aristotle is ‘the form of the body’, that which causes a body to live, which gives it structure and enables it to exercise its faculties. For other attempts to reformulate Aristotle’s view on the mind–body debate in modern terms see the volume by Nussbaum and Rorty (1992), with comprehensive bibliography. Heart, brain, blood, pneuma 129 does not prevent him from repeatedly speaking of ‘experiences typical to the soul’, activities a human being carries out ‘with his soul’, or perceptions which ‘penetrate the soul’. According to Aristotle, the functioning of the dual entity that body and soul constitute is governed by a large number of organs and material factors. The heart is assigned the role of ‘beginning’ or ‘origin’ (arche¯), both as a source of essential bodily heat (required among other things for the digestion of food) and as the seat of the central sense organ, which is connected with the limbs and the separate sense organs and co-ordinates the data it receives from them. He assumes interaction between the heart (to him the real seat of the mind), the brain (which plays a pivotal role in sense perception) and the so-called ‘psychic pneuma’, a delicate substance that is responsible for transmitting sensory and motor signals. Organs for perception, limbs and other parts of the body are assumed to be connected to each other and to a centre via cer- tain ‘passages’ (poroi, phlebes, neura). The assumption of the existence of this network of passages and the ideas about their course and ramifications are highly speculative and hardly based on what we would 21 On Youth and Old Age (De iuventute et senectute, De iuv. Yet the fact that this obser- vation was known both to the author of the Hippocratic work On Fleshes and to Aristotle, who nevertheless do not attribute any significant role in cognition to the brain, proves that it might equally give rise to other interpretations. The authors mentioned do in fact employ rather sophisticated termi- nology for what we would call psychological, mental or spiritual faculties, but they assume a close connection between these faculties and anatomical and physiological factors. When speaking about exercising these faculties, they virtually always do so in terms of certain substances (such as blood, air or water) or qualities (hot, cold, dry, wet) and of processes such as flowing and distributing or, in case the psychic faculties have been disturbed, of stagnation, constipation, blockage, and so on. Another recurring element is the emphasis on balance (isonomia, summetria, eukrasia) and on the risk of an excess or shortage of a certain substance or quality. An exception to this rule is Aristotle’s idea that the highest cognitive faculty, thought, is not bound to a physical substrate. It is a kind of epiphe- nomenon that, although it is unable to function without sense perception (and therefore without physiological processes), cannot be located in a par- ticular place of the body. The author of this presumably post-Aristotelian writing claims that gnome¯ ¯ (‘mind’, ‘insight’) has its seat in the left ventricle of the heart, from where it issues its decrees about ‘the other (part of the) soul’ (alle¯ psuche¯), which is situated in the rest of the body. To prove his stance, the author argues that if autopsy were carried out on a body of a living being that had just been killed, the aorta would still contain blood, but the left 28 See Lloyd (1979) 146–9; for views on the vascular system see the studies mentioned in Harris (1973) and Duminil (1983). As stated above, the heart is given a leading role in co-ordinating perception, movement and nutrition (see Part. For the problems raised by Aristotle’s view see Barnes (1971–2) 110–12, reprinted in Barnes, Schofield and Sorabji, vol. Heart, brain, blood, pneuma 131 ventricle would not;31 this maintains contact with the blood by means of a process of ‘evaporation’ and ‘radiation’. As we have seen before, the medical authors of the period we are discussing do not consider the question of the seat of the mind an isolated issue, but a matter that becomes relevant when treating diseases which, although they have a somatic cause like other diseases, also manifest themselves in psychic disor- ders. Of the four classic psychosomatic diseases, mania (a chronic disorder), phrenitis, melancholia and epilepsy, epilepsy was by far the most dreaded. It was also known as ‘the big disease’ or ‘the sacred disease’; possession by the gods seemed the obvious explanation, but at the same time the physical aspects of the disease were so prominent that there could be no doubt as to its pathological status (as opposed to mania and melancholia, which were considered to manifest themselves in positive forms as well). After a long philippic against those adhering to this view he expounds his own theory.

In central cyanosis, because the etiology is either re- duced oxygen saturation or abnormal hemoglobin, the physical findings include bluish discoloration of both mucous membranes and skin. In contrast, peripheral cyanosis is as- sociated with normal oxygen saturation but slowing of blood flow and an increased frac- tion of oxygen extraction from blood; subsequently, the physical findings are present only in the skin and extremities. Peripheral cyanosis is com- monly caused by cold exposure with vasoconstriction in the digits. Peripheral vascular disease and deep venous thrombo- sis result in slowed blood flow and increased oxygen extraction with subsequent cyanosis. Other common causes of central cyanosis include severe lung disease with hypoxemia, right-to-left intracardiac shunting, and pulmonary arteriovenous malformations.
