Ways 1 & 2: The arguments for an unmoved mover and uncaused causer
Concerned with why there is any motion or causation
Argues that there is a first mover which causes all that exists
Argues that there is a first mover which causes all that exists
God is the first efficient cause of the universe
Infinite regression is rejected
God is a pure act
Copleston called this an 'ontologically ultimate cause'
Way 3: The argument from contingency
Aquinas argues that God necessarily exists
Criticisms of Way 3:
Kant rejected Aquinas' Third Way for the same
reason that he rejected the concept of necessary
existence with respect to the ontological
argument
Mackie questioned the assumption that there is a necessary being & that God should be the necessary being
David Hume
Questioned idea that every effect has the same cause
One can't always claim/ assume that every effect has a necessary cause
The Fallacy of Composition
Hume questioned whether its necessary for the whole universe
to have a cause just because everything that is within the
universe could be explained by reference to a preceding cause
Bertrand Russell's example: the mother of the human race
Russell- Copleston debate
Copleston
Presented reformulation of some of the ideas found in 3rd Way of Aquinas
Argued the Universe can only be
sufficiently explained by reference to
God
God is different from contingent
beings as he is 'his own sufficient
cause'
Argued that explaining why there's a
universe is important
Russell
Rejected Copleston's arguments and suggested
that the universe was not explainable in the way
Copleston wanted
Argued that whether an explanation for
the universe as a whole is possible or not,
the explanation is beyond the reach of
human beings
It's unnecessary for human's have a
sufficient explanation of the universe that
goes beyond the contingent universe
Stated: "I should say that the universe is just there and that is all"
