But ‘conscience’ here did not mean primarily either the modern lay idea, or the ‘conscience’ of Christopher St German’s exposition. Rather, it referred to the judge’s, and the defendant’s, private knowledge of facts which could not be proved at common law because of medieval common law conceptions of documentary evidence and of trial by jury. The concept of http://ojls.oxfordjournals.org/ a jurisdiction peculiarly concerned with this issue allowed the ‘English bill’ procedure to be held back to a limited subject area rather than—as in Scotland and the Netherlands—overwhelming the old legal system. By the later 17th century, however, the concept of conscience had lost its specific content, leaving behind the problem, still with us, of justifying the separation of ‘equity’. 1. Introduction at University of Cambridge on January 19, 2015 When reading legal materials, there is no temptation to assume that ‘felony’ has a non-legal meaning, since it is a pure term of art, and there is little temptation to suppose that ‘fee simple’ means an uncomplicated price or that the ‘tenant in tail’ has a physical tail. However, ‘Conscience’ and ‘Equity’, when used of ‘courts of conscience’ and ‘courts of equity’, in particular, the Court of Chancery, seem to be particularly prone to attract the assumption that the words when used in a legal context have their ‘ordinary natural’ meaning. The point of this article is to try to explore some of the (possible) technical meanings of these words in their early use. It will become apparent (perhaps gradually) that ‘conscience’ is more helpful than ‘equity’ in understanding the jurisdictions in question; but that in this context its meaning may be some distance from its ordinary meaning. Of course, the modern technical meaning of ‘equity’ is merely ‘the rules which were applied in the Court of Chancery in 1875, as developed by the modern court system since’, but with some overtone, occasionally drawn on, of general fairness or justice as opposed to the letter of the law.1 * Fellow of St Hugh’s College, University of Oxford. 1 F.W.

However, in, and in relation to, the early modern Downloaded from period there are some attempts to make the concepts do more substantial intellectual work. 2. ‘Equity’/‘E""’ http://ojls.oxfordjournals.org/ It is convenient to start with ‘Equity’ both because it is the more general modern usage for the jurisdiction, and because it is ultimately less informative. It is well-known that the source of one version of ‘equity’ is the concept of ‘"""’ found in Aristotle’s Nichomachean Ethics, where the idea is explained in terms of the difficulty of making general definite rules cover the indefinite range of possible factual situations. ‘Equity’ is then like the lead ruler allegedly invented in ancient Lesbos, which adapts the fixed measurements (the terms of the law) to the irregular stone (the particular situation).4 This concept was at University of Cambridge on January 19, 2015 picked up by Aquinas,5 and was a commonplace of medieval legal thought.6 In Sir John Fortescue’s De Natura Legibus Naturae (1460s) it is linked with the idea that a king ruling ‘politically’, i.e. under law, must or may at some times rule ‘regally’, i.e. by absolute power.7 Its subsequent popularization in connection with the Chancery and analogous jurisdictions seems to have 2 E.g.

WINTER 2007 Equity and Conscience 661 been primarily due to its role in Christopher St German’s Doctor and Student (1523, 1531), where the activity of the Chancery is partially (and rather imperfectly or inconsistently) explained as an application of """; St German’s book was widely excerpted by subsequent lawyers writing on Chancery and equity.8 The difficulty with this approach has been identified episodically ever since, most recently by Georg Behrens.9 Aristotelian """ is merely one of the standard approaches to the judicial interpretation of legal rules, i.e. to consider their larger purpose in order to identify their application (or not) to the facts at issue. As such it was a commonplace argument, as ‘the equity of the statute’, in both the medieval Downloaded from and the early modern common law courts.10 It, therefore, fails to have explanatory power in relation to the particular activity of the Chancery. It is doing real work in St German’s argument, but it will be better to return to this a little later. There was a somewhat narrower and more powerful sense available to late http://ojls.oxfordjournals.org/ medieval and early modern lawyers. This was aequitas canonica, canonical equity, a doctrine of medieval canon law. Aequitas canonica probably did have some impact on the Chancery jurisdiction, but, as Barton explains in his discussion of it, it was hard to distinguish from conscientia.11 Certainly what survives of this doctrine in equity as later practised seems to be mainly the idea of general fairness and justice as overriding inconsistent positive law, which is almost as unhelpful as """ . at University of Cambridge on January 19, 2015 3. Conscience St German’s discussion of ‘conscience’ is not the only sense of the term used by lawyers—to this we will have to return—but is by far the most important for later lawyers’ explicit discussions of the topic. St German follows, albeit loosely, the medieval theologians. Synderesis is the faculty of moral reasoning, and conscience is the application of this faculty to particular cases. The role of conscience in law thus presupposes a natural law theory of the Thomist type— law ultimately gets its authority from objective morality based on the place of human beings and human society in the divine creation; synderesis/conscience gives the reasoning being direct access to this, and hence is capable of 8 The current standard edition is that edited by T.F.T.
