Of the properties of Relation.
HOw many properties doe belong to Relation?

Fiue: First, to haue contrarietie, as vertue and vice, sci∣ence and ignorance. But this propertie belongeth not to all: for double and the one halfe hath no contrarietie, nor the Father and the Sonne.

Page 39

What is the second propertie?

The second is to be more or lesse, as to bee more like, or lesse like; or more equall, or lesse equall. Yet this belongeth not to all: for double hath neither more or lesse, nor one Father is said to be more or lesse then another.

What is the third propertie?

The third is, that all Relatiues (which are Relatiues indeed) are conuertible: for he is a Father, that hath a Sonne, and hee is a Sonne, that hath a Father, &c.

What is the fourth propertie?

The fourth is, that one Correlatiue is not before another, but are both together: as the father is called no father, vntill he hath begotten a childe, and a childe is called no sonne, before he be be∣gotten of the father. For this is a generall rule of Correlatiues: If the one be, the other must needs be: If the one be taken away, the other must also be taken away.

What is the fift propertie?

The fift is, that whosoeuer assuredly knoweth the one Correla∣tiue, must needs know the other: for whosoeuer certainly know∣eth that I am a father, must needs also certainly know that I haue a childe. The like may be said of all that be Correlatiues indeed, to whom this propertie only belongeth, as Aristotle saith.
