Coke: the appeal to reason 13
the land, since 3 September 1189)7 The first was essentially rational, and
therefore intrinsically binding; the second was enacted by popular consent.
The first resembled the truths of mathematics; the second was a kind of
tacit statute. It was possible, however, to combine the two ideas. The
inherent adaptability of custom (unlike a rigid, because written, law) could
be seen as a guarantee that the system it created was a rational response to
local needs. This was certainly the view of Sir John Da vies (1569-1626),
who wrote that the English had 'made their own laws out of their wisdom
and experience (like a silkworm that formeth all her web out of her self
only)'.
8
It was the possibility that J. G. A. Pocock describes: that 'custom
might be idealised and described as perfect equity; the English common
lawyers virtually reached this point.'
9
The idea was extremely attractive
(not least to Matthew Hale), but Coke had a different approach.
The problem Coke addressed was best articulated by St German
(c. 1460—1541). For the great Henrician jurist, the common law proper was
'divers general customs of old time used through all the realm, which have
been accepted and approved by our sovereign lord the King and his
progenitors and all their subjects'.
10
A chapter later in the same discussion
he mentioned the main problem that this definition raised. The general
customs were 'the strength and warrant' (the Latin version has 'auctoritas')
of a number of rules he called 'maxims', which were unknown outside the
Inns of court.
11
'Authority', he had earlier explained, was crucial to the
making of every human law, because 'the sentence of a wise man doth not
bind the commonalty if he have no rule over them'.

These maxims were

politics of the ancient constitution: an introduction to English political thought
1603—
1642, 1992, esp. pp. 27-57. Burgess believes that all of common law was seen as both
reason and custom, though many of the customs were only known among the common
lawyers (pp. 34—5). He implicitly denies that the making of a custom in the first place
demanded a general popular consent. This theory is probably true of most earlier lawyers;
we are told that 'nowhere in the theory of Pecock and Fortescue or in the Year Books can
be found statements which regard the consent of the community as the basis for national
custom, the common law' (Norman Doe, Fundamental authority in late medieval law,
