[4.10.2] St Bonaventure on Ontological Truth

St Bonaventure ( the “Seraphic Doctor”, 1217 – 1274 AD), in the work Commentary on the Sentences of Lombard, presents a theory of ontological truth (see also [4.8]):

  • God created all things, so the whole universe existentially depends on God.
  • Ontological truth is “the indivision of act and potency,” taken in a hylomorphic context (see [1.3.5] and [4.9.2])
  • Since we don’t have a perfect indivision of the potency and act in creatures, they present a combination of created truth and falsity.
  • Because it has perfect unity, God presents no indivision and admixture, so he is the highest, uncreated truth.

Bonaventure’s model of ontological truth is presented in the following OntoUML diagram:

GodGod creates the creatures.
“If, however, truth is understood as that which admits no admixture, then only God is truth, for God is pure indivision or unity. In Him alone is there perfect imitation of unity, and pure expression with distinction”

CreatureAll creatures are created by God.
“All creatures are partial actualizations of truth.”
NatureNature (or essence) is the combunation of form and matter that make a creature what it fundamentally is, and without which it loses its identity.
“All creatures are true to the extent that they actualize the potential perfections of their natures, and they are false to the extent that they fail to do so, because ontological truth is ‘the indivision of act and potency.’ […] From rocks to angels, all creatures are true to the extent that the potencies of their “existence” given by matter are realized through the perfection of their “being” through form.”

FormForm is that which makes some matter which is potentially a Creature actually a Creature.

[4.10.1] St Bonaventure on Creatures as God’s Signs

St Bonaventure (the “Seraphic Doctor”, 1217 – 1274 AD), in the work Commentary on the Sentences of Lombard, writes about the ways how all created things signifies God:

  • God created all things, so the whole universe existentially depends on God.
  • All creatures act in the role of signs which point to God; these signs can be of four types.
  • Based on their properties, all creatures signify God as shadows and vestiges; more than that, rational creatures signify it as images and similitudes.
  • Rational creatures (humans, angels) have the power to look to these signs, which leads them to God. This way rational creatures “have God as their ultimate object, whereas all creatures have God as their Cause”.

Bonaventure’s model of creatures as God’s signs is pictured in the following OntoUML diagram:
