Question 1a: Descartes’ Causal Adequacy and Ontological Arguments & Their Relationship

René Descartes develops two fundamental philosophical arguments for the existence of God: the causal adequacy argument from Meditation 3 and the ontological argument from Meditation 5. Each presents a unique approach grounded in rationalist philosophy. The causal adequacy argument asserts that the cause of an idea must possess at least as much formal reality as the idea itself has virtual or objective reality. Since Descartes recognizes the idea of a perfect, infinite being—God—exists in his mind, he concludes that the cause of this idea must itself possess infinite reality. Because only a perfect being can possess the nature of perfect existence, this serves as proof of God’s existence. This argument relies heavily on rational insight and logical deduction, embodying Descartes’ rationalist method of deriving certainty through reason alone.

In contrast, the ontological argument in Meditation 5 builds upon the conceptual analysis of God’s essence. Descartes reasons that existence is a necessary attribute of a supremely perfect being; that is, if God is perfect, then God’s non-existence would be a contradiction. This argument is purely a priori, relying on the definition and conceptual coherence of God as a being with all perfections, including existence. Meditation 5 emphasizes that existence is not merely contingent but an inherent part of the concept of a perfect being.

Despite their differences, these two arguments are interconnected and exhibit how Descartes uses rationalism to establish divine existence. The causal adequacy argument appeals to the idea that the idea of God has a sufficient cause—namely, a perfect being—while the ontological argument suggests that the very concept of a perfect being entails its necessary existence. Both arguments reinforce each other within Descartes' broader rationalist framework, which holds that reason is the primary path to knowledge about fundamental truths, including God’s existence. They exemplify Descartes's commitment to rationalism—the view that reason and innate ideas are the primary sources of knowledge, as opposed to sensory experience.

Question 1b: Hume’s Empiricism and Its Contrast with Descartes

David Hume’s empiricism emphasizes that all knowledge originates from sensory experience. For Hume, ideas are derived from impressions—direct sensory perceptions—and are fundamentally inferior to perceptions in clarity and certainty. He also asserts a skeptical stance toward metaphysics, considering many metaphysical claims to be speculative, unfounded, and disconnected from experiential evidence. In Section 1 of Enquiries Concerning Human Understanding, Hume warns against the unwarranted proliferation of abstract concepts such as substance, causality, and the self, which he regards as products of imagination rather than empirical observation. Regarding religion and metaphysics, Hume is highly skeptical; he argues that such doctrines lack empirical basis and are often based on fear, ignorance, or superstition.

In Section 2, Hume explains that our ideas are ultimately derived from prior impressions. Regarding the idea of God, Hume contends that it originates from our sense of awe and admiration in observing the universe, compounded with incomplete impressions that become faint and blended into the idea of a supreme being. He suggests that this idea is constructed from prior experiences and imaginative associations rather than clear, distinct impressions. Thus, Hume's argument implies that belief in God is not rationally justified but rather a result of psychological tendencies.

When comparing Descartes and Hume, the key difference lies in their epistemological foundations. Descartes believes in innate ideas and a rational intuition that can lead to certain knowledge, including the existence of God, independent of sensory experience. Hume rejects innate ideas, emphasizing sensory-based origin of knowledge, and maintains that metaphysical claims lack logical and empirical justification. From a critical standpoint, Hume’s skepticism appears more consistent with scientific empiricism, as it demands empirical evidence for beliefs. Conversely, Descartes’ rationalism offers certainty but can be criticized for relying on purely logical, a priori deductions that may neglect empirical limitations.

In evaluating their arguments, Hume’s empiricism provides a more cautious and evidence-based approach, aligning with modern scientific methods. Descartes’ approach, while logically rigorous, relies heavily on innate ideas and rational intuition, which can be questioned for lacking empirical support. Thus, Hume’s skepticism about metaphysics and his emphasis on sensory evidence arguably offer a stronger philosophical stance in the context of scientific realism and rational inquiry.

Question 2: Hume’s Distinction and Comparison of Mathematical Ideas with Descartes

Hume’s epistemology hinges on the distinction between relation of ideas and matters of fact. Relation of ideas are a priori, necessary truths that are discoverable through reason alone—such as mathematical propositions or logical truths. Matters of fact depend on sensory experience, are contingent, and their truth is not necessary; they require empirical verification. This distinction is foundational because it delineates what can be known with certainty versus what is probabilistic.

Regarding mathematical ideas, Hume argues that they originate from impressions—specifically, the perceptions of our mental operations like intuition and deduction. Mathematical truths, for Hume, are relations of ideas because they are necessary, a priori, and derived from the logical structure of the mind’s operations. This contrasts with Descartes, who sees mathematical ideas as innate, rooted in the mind’s formal reality, and exemplified in Meditation 5 through the distinction between formal reality (the actual attribute of substances) and objective reality (the content of ideas). For Descartes, mathematical ideas are innate and serve as clear and distinct perceptions, exemplifying innate ideas that do not depend on sensory experience.

Specifically, Descartes considers mathematical ideas as innate, meaning they are present within the mind from the outset and do not require empirical observation. For example, the idea of the triangle’s angles summing to 180 degrees is an innate, formal idea that exists in the mind's rational structure. In Meditation 5, Descartes emphasizes that mathematical truths are necessary and universally true due to formal reality, which is rooted in the very nature of the mind’s rational capacity.

Hume, however, rejects the notion of innate ideas and argues that mathematical knowledge, while certain, arises from habit, custom, or mental associations based on prior sensory experiences. For Hume, mathematical ideas are not innate but are formed through the repeated perception of similar instances, leading to the development of relations of ideas based on experience. Consequently, for Hume, mathematical truth is contingent and derived from observable patterns, although it is highly reliable due to its logical rigor.

This difference has a fundamental implication: Descartes sees mathematical ideas as exemplars of innate, necessary truths derived from formal reality, while Hume views them as products of mental processes rooted in experience. The perception of innate ideas in Descartes underscores his rationalist belief in the mind’s capacity for pure reason, whereas Hume’s empiricism underscores reliance on sensory-derived habits and associations. This divergence reflects their broader epistemological commitments: rationalism versus empiricism.

In conclusion, mathematics exemplifies innate ideas for Descartes because they are considered part of the mind’s rational structure, necessary and universally true, as discussed in Meditation 5. For Hume, mathematical ideas are not innate but formed through experience and mental habits, emphasizing the importance of sensory input and empirical observation in knowledge acquisition.

Question 3: Is Existentialist Ethics Possible? Why or Why Not?

Existentialist ethics questions whether meaningful moral principles grounded in individual existence are attainable. Traditional moral systems rely on objective standards, universal rules, or divine commandments. In contrast, existentialist ethics emphasizes individual freedom, authentic choice, and personal responsibility in an absurd or indifferent universe. The core challenge is the apparent lack of predetermined moral structures, which seemingly leaves individuals alone in defining their ethical paths. Thus, the question arises: can ethics be truly existential, rooted solely in individual existence without external moral authorities?

Existentialist ethicists like Jean-Paul Sartre argue that authentic morality is indeed possible, but it requires individuals to confront the anguish of radical freedom and create their own values in a world without inherent meaning. The most powerful idea in existential ethics is the concept of "existence precedes essence,” which asserts that individuals first exist, then define themselves through their actions. This places moral responsibility squarely on personal choice, emphasizing authenticity and moral freedom. Sartre’s notion of radical freedom entails that individuals must constantly choose who they are, taking responsibility for these choices and their consequences. This does not suggest moral relativism but rather moral authenticity grounded in personal accountability.

However, critics might argue that this form of ethics risks nihilism or moral chaos, as it lacks external moral standards to guide behavior universally. Furthermore, the focus on individual choice can be criticized for neglecting social responsibilities and communal values. Nonetheless, existentialists contend that true morality arises when individuals act in good faith, embracing their freedom and acknowledging the weight of their choices.

In conclusion, existentialist ethics is possible when understood as a moral framework based on authentic individual choice and responsibility, rather than external moral dictates. The most powerful idea remains that moral values are not predetermined but are created through personal engagement and conscious decision-making. This perspective resonates with contemporary debates about authenticity, autonomy, and moral agency, emphasizing that ethical living involves embracing the freedom and burden of self-creation.
