Introduction to Philosophy
Free Will and Determinism: Some Varieties
Abstract: Some of the common philosophical and theological doctrines
concerning the extent to which persons have choices are briefly outlined
and discussed as a precursor and a background to our study of ethics.
- Introduction: Historically the morality of peoples has been, for the most part, been
based on cultural structure and religious doctrines. Moral values have differed among
various persons and groups of persons, in part, due to different political and
religious inculcation.
- If there is to be a philosophical basis for how we ought to lead
our lives and seek a good life, then this basis cannot be founded on the practices
found in different cultures. Morals are based on the ideal behavior practiced
among persons in various sociological groups and so is considered a descriptive
study of the proper way to think and act. In philosophical ethics, we are interested
in the question of how we should act, regardless of how persons actually do
behave. Hence, ethics is considered a prescriptive study of the proper
way to act. The distinction between prescriptive ethics and descriptive ethics or
morals is explained in more detail in the tutorial entitled in the tutorial entitled
Morals, Ethics, and Metaethics. The difficulties
with moral relativism are explained in more detail in the tutorial entitled
Ethical Relativism.
- If there is to be a philosophical basis for how we ought to lead
our lives and seek a good life, then this basis probably cannot be founded on the
existence God either. As we have seen, both á priori and
á posteriori proofs for God's existence are subject to substantial
philosophical objection—ethical principles cannot be reliably based on such
speculation. As well, different religions derive different ethics principles.
- Thus, our task in this part of the course is to see how far we can base ethical
principles on reason alone. Toward this end, it is important to mention as a
starting point that if scientific determinism were true (viz that every event has a
cause) and psychology were to be a science with exact predictability, it's quote
possible the whole enterprise of ethics would be moot. Without the possibility of
some free decisions, alternative courses of decision or action would not be possible.
- The philosophical positions on the problem of free will and determinism have been
many and various. In these notes, ten basics doctrines will be defined, characterized,
and outlined. These doctrines are defined in their basic forms; in practice, philosophies
utilizing these views are considerably more sophisticated than the accounts sketched
here.

Determinism. Carl Hoefer explains different definitions of determinism,
whether we can know if the universe is deterministic, and the role of
determinism in physics. Probability and the question of choice are also
discussed in this article from the Stanford Encyclopedia of
Philosophy.
- “Free
Will and Determinism” The philosophical history of the
free will debate is traced through Plato, Aristotle, Epicurus,
the Stoics, Augustine, Aquinas, Spinoza, Leibniz, Locke, Hume,
Kant, Bradley, Schlick, and Cambell by Bernard Berofsky in the Dictionary
of the History of Ideas maintained by the Electronic Text
Center at the University of Virginia Library.
- “Free
Will in Theology” Austin Farrer retraces the history of
the free will problem through the Sophists, Plato, Aristotle,
Epicurus, the Stoics, Augustine, and Kant. The linguistic approach
to the free will–determinism issue is also discussed in this
entry from the Dictionary
of the History of Ideas maintained by the Electronic Text
Center at the University of Virginia Library.
- “Determinism
in Theology: Predestination” A summary discussion of the
logical problems including the dilemma of the problem of evil in both
the Christian and non-Christian traditions is presented by Robert M.
Kingdon in the Dictionary
of the History of Ideas maintained by the Electronic Text
Center at the University of Virginia Library.
"We may regard the present state of the universe as the
effect of its past and the cause of its future. An intellect
which at any given moment knew all of the forces that
animate nature and the mutual positions of the beings
that compose it, if this intellect were vast enough to
submit the data to analysis, could condense into a single
formula the movement of the greatest bodies of the universe
and that of the lightest atom; for such an intellect nothing
could be uncertain and the future just like the past would
be present before its eyes." --Laplace, Essai
philosophique sur les probabilités
