Religion and Spirituality
Theology is the study of a god or gods and the nature of the divine. Whether there is a god (monotheism), many gods (polytheism) or no gods (atheism), or whether it is unknown or unknowable whether any gods exist (agnosticism; apophatic theology), and whether a divine entity directly intervenes in the world (theism), or its sole function is to be the first cause of the universe (deism); these and whether a god or gods and the world are different (as in panentheism and dualism), or are identical (as in pantheism), are some of the primary metaphysical questions concerning philosophy of religion.
Within the standard Western philosophical tradition, theology reached its peak under the medieval school of thought known as scholasticism, which focused primarily on the metaphysical aspects of Christianity. The work of the scholastics is still an integral part of modern philosophy, with key figures such as Thomas Aquinas still playing an important role in the philosophy of religion.
The Nature of Metaphysics
Some philosophers, such as Amie Thomasson, have argued that many metaphysical questions can be dissolved just by looking at the way we use words; others, such as Ted Sider, have argued that metaphysical questions are substantive, and that we can make progress toward answering them by comparing theories according to a range of theoretical virtues inspired by the sciences, such as simplicity and explanatory power.

Necessity and Possibility
Metaphysicians investigate questions about the ways the world could have been. David Lewis, in “On the Plurality of Worlds,” endorsed a view called Concrete Modal realism, according to which facts about how things could have been are made true by other concrete worlds, just as in ours, in which things are different. Other philosophers, such as Gottfried Leibniz, have dealt with the idea of possible worlds as well. The idea of necessity is that any necessary fact is true across all possible worlds. A possible fact is true in some possible world, even if not in the actual world. For example, it is possible that cats could have had two tails, or that any particular apple could have not existed. By contrast, certain propositions seem necessarily true, such as analytic propositions, e.g., “All bachelors are unmarried.” The particular example of analytic truth being necessary is not universally held among philosophers. A less controversial view might be that self-identity is necessary, as it seems fundamentally incoherent to claim that for any x, it is not identical to itself; this is known as the law of identity, a putative “first principle”. Aristotle describes the principle of non-contradiction, “It is impossible that the same quality should both belong and not belong to the same thing … This is the most certain of all principles … Wherefore they who demonstrate refer to this as an ultimate opinion. For it is by nature the source of all the other axioms.”

Volunteer Information Session
Monthly information sessions provide an opportunity for us to present the wide range of volunteer opportunities, provide a “big picture” of our programs and then allow you to “interview” us to ensure that we can provide what you are looking for in a volunteer experience.
Volunteer Orientation Sessions typically occur on the last Friday of each month. They start at 2:00pm and are generally one hour in length. These sessions provide information about our volunteer opportunities, expectations of our volunteers, and what you can expect from us. They are highly recommended if you are considering applying for a volunteer position at the Aphasia Institute.

Mind and Matter
The nature of matter was a problem in its own right in early philosophy. Aristotle himself introduced the idea of matter in general to the Western world, adapting the term hyle, which originally meant “lumber.” Early debates centered on identifying a single underlying principle. Water was claimed by Thales, air by Anaximenes, Apeiron (the Boundless) by Anaximander, fire by Heraclitus. Democritus, in conjunction with his mentor, Leucippus, conceived of an atomic theory many centuries before it was accepted by modern science. It is worth noting, however, that the grounds necessary to ensure validity to the proposed theory’s veridical nature were not scientific, but just as philosophical as those traditions espoused by Thales and Anaximander.
The nature of the mind and its relation to the body has been seen as more of a problem as science has progressed in its mechanistic understanding of the brain and body. Proposed solutions often have ramifications about the nature of mind as a whole. René Descartes proposed substance dualism, a theory in which mind and body are essentially different, with the mind having some of the attributes traditionally assigned to the soul, in the seventeenth century. This creates a conceptual puzzle about how the two interact (which has received some strange answers, such as occasionalism). Evidence of a close relationship between brain and mind, such as the Phineas Gage case, have made this form of dualism increasingly unpopular.
Another proposal discussing the mind-body problem is idealism, in which the material is sweepingly eliminated in favor of the mental. Idealists, such as George Berkeley, claim that material objects do not exist unless perceived and only as perceptions. The “German idealists” such as Fichte, Hegel and Schopenhauer took Kant as their starting-point, although it is debatable how much of an idealist Kant himself was. Idealism is also a common theme in Eastern philosophy. Related ideas are panpsychism and panexperientialism, which say everything has a mind rather than everything exists in a mind. Alfred North Whitehead was a twentieth-century exponent of this approach.
Idealism is a monistic theory which holds that there is a single universal substance or principle. Neutral monism, associated in different forms with Baruch Spinoza and Bertrand Russell, seeks to be less extreme than idealism, and to avoid the problems of substance dualism. It claims that existence consists of a single substance that in itself is neither mental nor physical, but is capable of mental and physical aspects or attributes – thus it implies a dual-aspect theory.
For the last one hundred years, the dominant metaphysics has without a doubt been materialistic monism. Type identity theory, token identity theory, functionalism, reductive physicalism, nonreductive physicalism, eliminative materialism, anomalous monism, property dualism, epiphenomenalism and emergence are just some of the candidates for a scientifically informed account of the mind. (It should be noted that while many of these positions are dualisms, none of them are substance dualism.)
Prominent recent philosophers of mind include David Armstrong, Ned Block, David Chalmers, Patricia and Paul Churchland, Donald Davidson, Daniel Dennett, Fred Dretske, Douglas Hofstadter, Jerry Fodor, David Lewis, Thomas Nagel, Hilary Putnam, John Searle, John Smart, Ludwig Wittgenstein, and Fred Alan Wolf.

Central Questions
Identity and Change
The Greeks took some extreme positions on the nature of change: Parmenides denied that change occurs at all, while Heraclitus thought change was ubiquitous: “[Y]ou cannot step into the same river twice.”
Identity, sometimes called Numerical Identity, is the relation that a “thing” bears to itself, and which no “thing” bears to anything other than itself (cf. sameness). According to Leibniz, if some object x is identical to some object y, then any property that x has, y will have as well. However, it seems, too, that objects can change over time. If one were to look at a tree one day, and the tree later lost a leaf, it would seem that one could still be looking at that same tree. Two rival theories to account for the relationship between change and identity are Perdurantism, which treats the tree as a series of tree-stages, and Endurantism, which maintains that the tree – the same tree – is present at every stage in its history.

Cosmology and Cosmogony
Metaphysical Cosmology is the branch of metaphysics that deals with the world as the totality of all phenomena in space and time. Historically, it has had quite a broad scope, and in many cases was founded in religion. The ancient Greeks drew no distinction between this use and their model for the cosmos. However, in modern times it addresses questions about the Universe which are beyond the scope of the physical sciences. It is distinguished from religious cosmology in that it approaches these questions using philosophical methods.
Cosmogony deals specifically with the origin of the universe.
Modern metaphysical cosmology and cosmogony try to address questions such as:
- What is the origin of the Universe? What is its first cause? Is its existence necessary? (see monism, pantheism, emanationism and creationism)
- What are the ultimate material components of the Universe? (see mechanism, dynamism, hylomorphism, atomism)
- What is the ultimate reason for the existence of the Universe? Does the cosmos have a purpose?
Determinism and Free Will
Determinism is the philosophical proposition that every event, including human cognition, decision and action, is causally determined by an unbroken chain of prior occurrences. It holds that nothing happens that has not already been determined. The principal consequence of the deterministic claim is that it poses a challenge to the existence of free will.
The problem of free will is the problem of whether rational agents exercise control over their own actions and decisions. Addressing this problem requires understanding the relation between freedom and causation, and determining whether the laws of nature are causally deterministic. Some philosophers, known as Incompatibilists, view determinism and free will as mutually exclusive. If they believe in determinism, they will therefore believe free will to be an illusion, a position known as Hard Determinism. Proponents range from Baruch Spinoza to Ted Honderich.
Others, labeled Compatibilists, believe that the two ideas can be reconciled coherently. Adherents of this view include Thomas Hobbes and many modern philosophers such as John Martin Fischer.
Incompatibilists who accept free will but reject determinism are called Libertarians, a term not to be confused with the political sense. Robert Kane and Alvin Plantinga are modern defenders of this theory.

Central Questions
Most positions that may be taken with regards to any of the following questions are endorsed by one or another notable philosopher. It often is difficult to frame the questions in a non-controversial manner.
Being, Existence and Reality
The nature of Being is a perennial topic in metaphysics. For instance, Parmenides taught that reality is a single unchanging Being. The twentieth century philosopher Heidegger thought previous philosophers had lost sight of the question of Being (qua Being) in favour of the questions of beings (existing things), and that a return to the Parmenidean approach was needed. An ontological catalogue is an attempt to list the fundamental constituents of reality. The question of whether or not existence is a predicate has been discussed since the Early Modern period, not the least, in relation to the ontological argument for the existence of God. Existence, that something is, has been contrasted with essence, the question of what something is. Reflections on the nature of the connection and distinction between existence and essence dates back to Aristotle’s Metaphysics, and later, found one of its most influential interpretations in the ontology of the eleventh century metaphysician Avicenna (Ibn Sina). Since existence without essence seems blank, it is associated with nothingness by philosophers such as Hegel.

Origins and Nature of Metaphysics
Although the word “metaphysics” goes back to Aristotelian philosophy, Plato himself credited earlier philosophers with dealing with metaphysical questions. The first known philosopher, according to Aristotle, is Thales of Miletus, who taught that all things derive from a single first cause or Arche.
Metaphysics as a discipline was a central part of academic inquiry and scholarly education even before the age of Aristotle, who considered it “the Queen of Sciences.” Its issues were considered no less important than the other main formal subjects of physical science, medicine, mathematics, poetics and music. Since the beginning of modern philosophy during the seventeenth century, problems that were not originally considered within the bounds of metaphysics have been added to its purview, while other problems considered metaphysical for centuries are now typically subjects of their own separate regions in philosophy, such as philosophy of religion, philosophy of mind, philosophy of perception, philosophy of language, and philosophy of science.
Numbers
Commentary from Sir William Smith, Dictionary of Greek and Roman Biography and Mythology (1870, p. 620).
- Pythagoras resembled greatly the philosophers of what is termed the Ionic school, who undertook to solve by means of a single primordial principle the vague problem of the origin and constitution of the universe as a whole. But, as did Anaximander, he abandoned the physical hypotheses of Thales and Anaximenes, and passed from the province of physics to that of metaphysics, and his predilection for mathematical studies led him to trace the origin of all things to number, this theory being suggested, or at all events confirmed, by the observation of various numerical relations, or analogies to them, in the phenomena of the universe. “Since of all things numbers are by nature the first, in numbers they (the Pythagoreans) thought they perceived many analogies to things that exist and are produced, more than in fire, and earth, and Avater; as that a certain affection of numbers was justice; a certain other affection, soul and intellect; another, opportunity; and of the rest, so to say, each in like manner; and moreover, seeing the affections and ratios of what pertains to harmony to consist in numbers, since other things seemed in their entire nature to be formed in the likeness of numbers, and in all nature numbers are the first, they supposed the elements of numbers to be the elements of all things”.
- Brandis, who traces in the notices that remain more than one system, developed by different Pythagoreans, according as they recognised in numbers the inherent basis of things, or only the patterns of them, considers that all started from the common conviction that it was in numbers and their relations that they were to find the absolutely certain principles of knowledge, and of the objects of it, and accordingly regarded the principles of numbers as the absolute principles of things; keeping true to the common maxim of the ancient philosophy, that like takes cognisance of like. Aristotle states the fundamental maxim of the Pythagoreans in various forms.

What do Volunteers Do?
Conversation facilitation:
Working with groups of 4 – 6 people with aphasia, volunteers enable members to interact, engage, challenge and develop amazing conversations. Always working in partnership with another co-facilitator, your role is to provide communication techniques specific to the members with aphasia, while also taking part in the conversation. This is an integral position in our program and a great starting place for new volunteers.
Other volunteer opportunities include:
Painting/Creative Program Assistant; Fitness Assistant; Book Group Co-facilitator; Introductory Program Facilitators; One-to-One Computer Facilitator; Outreach Home-Visit Communication Facilitators.
There are also positions available in the areas of research, administration, fundraising, and governance.
