In the days before the Third Programme changed its name and nature to those of Radio 3, there were occasional broadcast discussions by a group called the Epiphany Philosophers. Since 1966 they have been publishing a journal whose title and sub-title point to the large questions with which the group has continued to be concerned: Theoria to Theory: An International Journal of Science, Philosophy and Contemplative Religion. The editors are conscious of the risks but also of the need to take them:‘We are not now seen as so “way out” as we used to be, because more people are realizing that one has got to go “way out”, and that what is “in” is culturally more dated than some powerful forces would have us believe’. The latest issue (June 1981) is also to be the last, though there is hope of continuing the good work in other ways. The journal itself may be revived ‘in a new form as a much cheaper production’ (the current subscription is £30 for a volume of four issues of 88 pages). There is also a plan under which the publishers, Gordon and Breach, will publish a series of books designed to ‘promote the exploration of new ideas and new applications in philosophy and science through continuing co-operation between philosophers and scientists in different disciplines’. Among the halfpromised volumes is one on The Athletics of Old Age, ‘seen as a spiritual as well as a mental and physical matter’. Others are Revisionary Metaphysics and Revisionary Science, What is Wrong with Contemporary Physics? and How can we move beyond Neo-Darwinism in Biology?.

Almost everybody has a conscience, though it may not play a dominating or even very prominent role in his life. To have a conscience is to classify some kinds of action as morally right and others as morally wrong, and to be disposed to do the former and avoid doing the latter. To judge an action as morally right or wrong is not to judge it as advantageous or disadvantageous to the agent; the motive for acting conscientiously cannot be pure self-interest. It is a mark of my thinking an action morally right that I am disposed to do it even though doing it will involve me in a net loss of enjoyment or a net surplus of suffering. A man who is only disposed to do such things as he thinks will increase his happiness in the long run has no conscience. (I do not include among these people those who think that it will be to their ultimate advantage to do what their consciences tell them would be right apart from considerations of ultimate advantage.) Conscience presents itself to a person as a kind of constraint which he cannot evade on the ground that it will be inconvenient to comply with it.

During the period from Descartes to Rousseau, the mind changed. Its domain was redefined; its activities were redescribed; and its various powers were redistributed. Once a part of cosmic Nous, its various functions delimited by its embodied condition, the individual mind now becomes a field of forces with desires impinging on one another, their forces resolved according to their strengths and directions. Of course since there is no such thing as The Mind Itself, it was not the mind that changed. Conceptions of the mind changed. Yet even to say this is misleading, because it suggests that somewhere out there in nowhere there is Nous, Psyche, Soul or Mind, the true but opaque object of all these conceptions. But of course there is no Mind in the realm of things in themselves, waiting for us to see it truly, like a China of the noumenal world, amused that our various conceptions reveal as much about ourselves as about it.

‘The door's being shut made the room warmer.’ What does it mean and what are our reasons for saying it? There is much agreement that singular statements of cause and effect are conditional statements, and also that they are more than that, but at this early moment of inquiry the agreement ends. Can it not be carried further?

It is necessary that, if the world is divided into nations, conflicts should arise in which there is no strong argument against terrorism or repression. By a strong argument I mean one that would sway all minds not blindly partisan, without moral commitments that are unusual or outlandish in the modern world and with as much aversion to violence as most people have. So I do not here consider, because it is unusual, heroic and absolute pacifism, much as I respect it; on the other hand I do mention Christian moral objections applying specially to terrorism because it seems somewhat outlandish even now to ignore the Christian element in our tradition.

Gallant hero of romantic film, who has just killed his equally gallant antagonist in a duel: ‘Was I wrong, father?’ Father (Yul Brynner): ‘You were both wrong; and you were both right, too.’

David Hume, speaking of moral sceptics, once said ‘And as reasoning is not the source, whence either disputant derives his tenets; it is in vain to expect, that any logic, which speaks not to the affections, will ever engage him to embrace sounder opinions‘. I am guilty of an inconsistency of some kind in quoting the above passage from Hume with approval for, though everything Hume wrote ought to be quoted with approval, it is inconsistent to approve of advice, and then immediately to disregard it. I am also guilty of an inconsistency of another kind. Once upon a time I myself defended a version of moral scepticism, but I can say in mitigation of this deplorable act that my tongue was partly in my cheek at the time, which is where one's tongue should be on the occasion of addressing the Joint Session of the Mind Association and the Aristotelian Society.

‘It seems an unaccountable pleasure’, Hume writes, ‘which the spectators of a well-written tragedy receive from sorrow, terror, anxiety, and other passions that are in themselves disagreeable and uneasy. The more they are touched and affected, the more are they delighted with the spectacle; and as soon as the uneasy passions cease to operate, the piece is at an end.’ It is with this opening remark that Hume introduces the main subject of his essay, ‘Of Tragedy’. In that essay he attempts to account for the pleasure spectators of well-written tragedies receive, i.e. he attempts to solve what might aptly be called the ‘delightful tragedy’ problem, which, in essence, is the paradoxical phenomenon of pleasure being aroused from the ‘bosom of uneasiness’. In this paper I shall critically analyse Hume's solution to the problem; the ultimate point of my discussion will be to determine whether his solution is adequate. I shall begin by focusing briefly upon two accounts of the paradoxical pleasure which Hume mentions and criticizes. Then I shall set out and analyse Hume's own account, and thereby determine its adequacy.

Are there circumstances in which we would be justified in taking one person's life for the sake of others? I am not here concerned with cases of self-defence, or what we might call ‘other-defence’, where one person has to be killed to prevent him taking the lives of others. Nor am I concerned with cases of self-sacrifice, or suicide more generally, or euthanasia; nor with capital punishment, or killing in warfare; nor even, for reasons we shall explore, with abortion. I am concerned with those cases where several people have an equal claim or right to life, the same claim or right which we typically accord to all human beings, but where not all can survive. In short we are faced with a choice, as to who shall live and who shall die.

We often, in effect, take it for granted that some word or phrase is what is called ‘the name of a class, be that class empty or non-empty’. We do so whenever in effect we either wonder about, or mean to be taking a view on, the number of members a certain suppositious class has, on the ultrasimple number scale: ‘None, more than none’.

In his article ‘Saints and Heroes’, Urmson argues that traditional moral theories allow at most for a threefold classification of actions in terms of their worth, and that they are therefore unsatisfactory. Since the conclusion of his argument has led to the widespread use of the term ‘acts of supererogation’, and since I do not believe that such acts exist, I propose to argue that the actions with which he is concerned not only can, but should, be contained within the traditional classification.

In recent years philosophers have given much attention to the ‘ontological problem’ of events. Donald Davidson puts the matter thus: ‘the assumption, ontological and metaphysical, that there are events is one without which we cannot make sense of much of our common talk; or so, at any rate, I have been arguing. I do not know of any better, or further, way of showing what there is’. It might be thought bizarre to assign to philosophers the task of ‘showing what there is’. They have not distinguished themselves by the discovery of new elements, new species or new continents, nor even of new categories, although there has often been more dreamt of in their philosophies than can be found in heaven or earth. It might appear even stranger to think that one can show what there actually is by arguing that the existence of something needs to be assumed in order for certain sentences to make sense. More than anything, the sober reader will doubtlessly be amazed that we need to assume, after lengthy argument, ‘that there are events’.

It has been argued that even if miracles such as those recorded in the Bible do occur, it does not follow necessarily that God is the author of them. One alternative to the theistic interpretation, so the argument goes, is that a candidate miracle is really an undisclosed extension of natural law. If, on the other hand, it can be shown either that miracles cannot occur or that the evidence for them can never be strong enough to warrant their rational acceptance, then the question of God's authorship becomes superfluous. Here I shall not be concerned with the question of theistic interpretation but with the logically more fundamental question of whether or not miracles can have occurred. Hume and some of his philosophic children in our day have tried unsuccessfully to establish the impossibility of miracles on the sole basis of an appeal to the concepts of miracle and natural law. If my argument is correct, their failure illustrates graphically the pitfalls in trying to solve an empirical problem by definition.

How does the study of society relate to the study of the people it comprises? This longstanding question is partly one of method, but mainly one of fact, of how independent the objects of these two studies, societies and people, are. It is commonly put as a question of reduction, and I shall tackle it in that form: does sociology reduce in principle to individual psychology? I follow custom in calling the claim that it does ‘individualism’ and its denial ‘holism’.

It is commonly believed that there are, in the world, large numbers of objects which occupy three-dimensional space. It is also commonly believed that at least a large part of people's experience is of the surfaces of these material objects. Nevertheless, arguments have been adduced in favour of the view that we are never aware of such surfaces but only of distinct items called ‘sense-data’. It has also been suggested that if we couple the view that experience is limited to sense-data with an empiricist thesis to the effect that knowledge is limited by experience then we are forced to the conclusion that we cannot have any knowledge of material objects. There have been many attempts to reconcile the sense-data thesis with common beliefs about material objects. Among them have been representative realism and phenomenalism. However, a view which may have found favour recently is the Quinean one that ‘the myth of physical objects is epistemologically superior to most in that it has proved more efficacious than other myths as a device for working a manageable structure into the flux of experience’.1

One of the greatest of Hume's philosophical achievements, which becomes in its turn an assumption presupposed by some of the others, is perhaps best stated at the end of the First Enquiry: ‘If we reason a priori, anything may appear able to produce anything. The falling of a pebble may, for aught we know, extinguish the sun; or the wish of a man control the planets in their orbits. It is only experience, which teaches us the nature and bounds of cause and effect, and enables us to infer the existence of one object from that of another’ (XII (iii) 164).

Every body cell of an animal or human being contains the same complete set of genes. In theory any of these cells can be used to start a new embryo. The technique has been employed in the case of frogs. The nucleus is taken out of a body cell of a frog and implanted in an enucleated frog's egg. The resulting egg cell is stimulated to develop into a normal frog, and will be an exact copy of that frog which provided the nucleus with all the genetic information. In normal sexual reproduction, two parents each contribute half their genes, but in the case of cloning, one parent passes on all his or her genes.
