John Duns Scotus
The 'Subtle Doctor' — univocity of being, 'thisness', and the primacy of the will.
Overview
A Franciscan of famous subtlety, Duns Scotus developed one of the most rigorous and original scholastic systems (Scotism), rivalling Thomism. He argued that 'being' is predicated univocally of God and creatures, introduced the 'formal distinction', defended the primacy of the will and love over intellect, championed individual 'thisness' (haecceity) as the principle of individuation, and gave a celebrated argument for the Immaculate Conception. His precision reshaped later medieval and modern metaphysics.
What they supported — and why
The univocity of being
Supported'Being' has one single meaning applying to God and creatures alike, though they differ infinitely.
WhyUnless being were univocal, no concept could bridge God and creatures, and natural knowledge of God would be impossible.
Haecceity ('thisness')
SupportedWhat individuates a thing is a unique positive 'thisness', not its matter.
WhyA common nature needs a further positive principle to become this particular individual, not merely undifferentiated matter.
The primacy of will and love
SupportedThe will is higher than the intellect; love of God surpasses knowledge, and God's own will grounds the moral order.
WhyThe will is self-determining and love is the highest act, so freedom and love take precedence over cognition.
Causes championed
- Metaphysical precision
- The natural knowability of God
- The primacy of will and love
Issues wrestled with
- Is 'being' said univocally of God and creatures?
- What individuates things?
- Is will or intellect primary?
Hurdles faced
- The extreme difficulty of his thought (which earned both 'Subtle Doctor' and, unfairly, the word 'dunce')
- An early death at about forty-two
