David Hume’s Philosophy: Empiricism, Skepticism, and Human Nature
David Hume’s Philosophy
Critique of Knowledge
Hume establishes several key principles regarding knowledge:
- Empiricist Principle: Experience is the source and limit of our knowledge. Knowledge arises from experience, rejecting the innate ideas proposed by rationalism. The human mind begins as a tabula rasa upon which experiences are imprinted.
- Immanence Principle: We perceive representations of things through our senses, not the things themselves. Perceptions are divided into impressions (intense, undeveloped
Kantian Ethics: A Deep Dive into Morality
Kantian Ethics: The human being is a theoretical user of reason, but also makes practical use of it. Humans are not only beings who know, but beings who act and use reason to guide and direct their actions. Reason becomes pure practical reason when guiding the will.

- If doubting everything is possible, then doubting doubt itself is also possible.
- If truth exists,
Rationalism: Core Principles and Descartes’ Modern Philosophy
Rationalism: General Characteristics
Rationalism is the philosophical theory that inaugurates modernity. Seventeenth-century philosophical rationalism essentially belongs to Descartes. Rationalism can be broadly defined as the philosophy that defends reason as the primary source of knowledge. A rationalist philosopher typically defends these basic theses:
- Confidence in reason is a basic element inherited from the Renaissance. Reason is objective, universal, and necessary, unlike faith and tradition.
Descartes’ Philosophy: Doubt, Certainty, and the Mind-Body Problem
Doubt and Certainty
In Descartes’s philosophy, doubt is the starting point. Convinced that everything must undergo a critical review, he begins to doubt everything (as presented in Part 3 of Discourse on the Method). Cartesian doubt differs from skepticism because it is methodical and preliminary: one must hesitate before reaching certainty, and doubt destroys itself to generate certainty. First, truths susceptible to the senses are rapidly dismissed (rejecting the rationalism characteristic of sensitive
