St. Thomas Aquinas: Faith, Reason, and the Five Ways to God
Faith and Reason
According to St. Thomas Aquinas, there is only one truth, originating from God. He distinguishes between faith, based on divine revelation and attained through grace, and reason, achieved through human intellect. While distinct, faith and reason intersect on common ground, with reason subject to and complemented by faith.
St. Thomas identifies two types of propositions:
- Truths demonstrable only through reason (preambles of faith), such as God’s existence, the soul’s immortality, and
Kant’s Philosophy: Reality, Knowledge, and Morality
Phenomenal and Noumenal Reality
We can only know subjective reality (the phenomenon), while the true reality (the noumenon) remains unknowable. This is a core principle of Kant’s philosophy.
Synthesis of Empiricism and Rationalism
Kant synthesizes empiricism and rationalism, arguing that knowledge arises from both experience and thought. A priori and a posteriori elements are essential for understanding.
Categories of Understanding
Our minds possess inherent categories, similar to those of Aristotle

His theory of knowledge supports an empiricist

Hume: Imagination and Representation
For Locke, representations in our minds are caused by material objects. Hume disagrees, arguing that we only know representations, not the external world. The principle of causality applies only between representations; we cannot use it to connect representations with something beyond empirical experience.
Hume’s Criticism of Substance
Empiricists view matter as obscure. Hume argues that substance, the concept of an object’s identity and persistence, is beyond

Freedom in Action
The Meaning of Action in the World
Freedom in Action begins with the premise that man lives in the world. This “world” isn’t merely a system of cause and effect, but an “arena full of meaning” where we act. Inhabiting the world means acting, not just responding to stimuli, but also inventing and creating without predetermined instincts.
Humans belong to an “open” and constantly “creating” species, as Pico della Mirandola posited during the Renaissance. The central question becomes:

Terms for Understanding Descartes’ Text
Opinion
Contrary to Platonic ideals, opinion represents uncertain knowledge based on questionable premises. Descartes views opinions as trials lacking proof, relying solely on probable reasons. Methodical doubt challenges pre-existing opinions, aiming to replace them with more valid understandings.
Reason
Reason, synonymous with “good sense” (bona mens), is the innate human faculty enabling sound judgment and discernment between truth and error. It forms the
