Characteristics of Scientific Knowledge

Scientific knowledge is philosophically opposed to any kind of dogmatism. It requires specific conditions for the validity of its postulates, which must be obtained through reflection and empirical evidence, expressed through logical reasoning, and directed toward objects intended to be known. It differs from other forms of knowledge in both its methodology and the instruments used.

Scientific knowledge is characterized as:

• Rational
• Orderly
• Systematic
• Verified
• Fallible
• Searching for regularities

Key Principles of Scientific Knowledge

Scientific knowledge possesses two primary characteristics:

1. Empirical Validation: It is the result of a contract between theory and empirical data. This means the only valid knowledge

• The Illusion of Self and Identity

  Hume argues that the self is not a simple, enduring entity. The mind confuses the ideas of "identity" and "succession." Memory allows us to recall past impressions, creating a succession of different views. We then mistakenly ascribe these to a single "subject," confusing succession with identity. Hume rejects the idea of a soul, deeming the question of immortality superfluous.

• Hume on God and Divine Substance

  Hume's position on God aligns with his views on the world and the soul. In Section XI of "An Enquiry Concerning Human Understanding," he addresses God and the afterlife, considering criticisms of substance and causality. Hume denies the validity of metaphysical proofs for God's existence, asserting that

Simple and Complex Ideas: Laws of Association

1. Simple Ideas

Simple ideas are indivisible sets of impressions, such as color, smell, or taste. They do not support distinction or separation.

2. Complex Ideas

Complex ideas are formed by the combination, aggregation, or grouping of simple ideas. This is not done in a fortuitous or arbitrary way, but by virtue of the association of ideas, a trend governing how simple ideas combine.

3. The Association of Ideas

For complex ideas to form in the mind, simple ideas must associate through psychic rules:

• Similarity and Dissimilarity
• Spatiotemporal Contiguity
• Cause and Effect

By classifying the elements of knowledge into impressions and ideas, Hume laid the foundations of radical empiricism. This approach introduces... Continue reading "Hume's Empiricism: Impressions, Ideas, and Knowledge" »

Happiness and Justice

Aristotle says that every action and choice aim at some good. But there are many goods and purposes of a very different nature. Happiness, or the good, seems, then, to be that toward which all actions constituting human life are directed and ordered. Just as we are necessarily moral, we are also inclined toward happiness. Human beings by nature tend toward happiness. Happiness, for one, may be money and wealth; for another, political power. The disposition of justice is that by which people practice what is right and want to act fairly and justly. Justice is variable, encompassing different forms such as:

• Justice as a virtue
• Quality of social order
• Commutative justice
• Distributive justice
• Legal justice

The Fundamental Concept of Law

All our activities governed by the law are considered legal activities. The law aims to regulate relations between people so that conflicts are resolved through the force of reason rather than physical force. It is a decisive factor in human civilization. As the classic adage suggests: "Where there is society, there is law."

Every individual living in society requires a set of standards or "rules of the game." Man is essentially a legal animal; the law is bound to the human experience. While the law may regulate the rights of animals, the differentiating factor is that only humans possess a legal character, as it is humanity that sets the standards and establishes the law.

The Scope of Governing Law

The law regulates... Continue reading "Fundamental Principles and the Nature of Law" »

Explanatory Models of Knowledge

Realism: Reality (the object to be known) exists independently and is not dependent on the subject. It implies the existence of the world. The person has an open mind and believes that the ability to understand lies within oneself and to know things as they are. Moreover, they possess a natural, spontaneous, and confident attitude.

Idealism: We know as we perceive, depending on the individual. A fly perceives differently from us, so its way of knowing is different. Idealism questions the existence of the world. The person believes that the ability to understand depends on the individual, and knowledge depends on the way one perceives. They adopt an artificial, voluntary, and critical attitude towards learning.

Descartes' Proofs for God's Existence

René Descartes, starting from the doubt in his own mind, which indicates imperfection, raises questions about the origin of the idea of perfection within him. He doubts everything except his own existence, recognizing his imperfection. Thus, since this idea cannot come from nothing or from himself (being imperfect), Descartes concludes that it must come from a perfect being, God, who has "put us in as the seal of the architect."

The Argument from the Idea of Perfection

This is the first demonstration of God's existence: the idea of perfection must be given by a perfect being. Since we, as imperfect beings, possess this idea but do not embody perfection, the idea must originate from God.

God as Guarantor of

Hume's Critique of the Idea of Substance

We must ask what impression derives from this idea? We cannot assign any impression to this idea. It has no reality, as the limits of our knowledge are the impressions themselves. Hume is therefore eliminating innate ideas and rejecting abstract ideas.

Impressions are always those that precede and supply the whole idea. Imagination makes its first appearance in a previous appearance. Therefore, the idea of substance can only come from our imagination, not derived from any sensitive impression.

Hume argues that the idea of substance is merely a collection of simple qualities to which we apply a particular name to remember them. This does not mean that substance is a surviving entity or a metaphysical concept.... Continue reading "David Hume's Empirical Philosophy: Substance and Causality" »

In paragraph 2, Article 19 No. 9, provisions are made for the protection of free, equal access to the promotion, protection, and restoration of health and rehabilitation of the individual. This encompasses the following:

a) Promotion:

The state meets this responsibility through the implementation of public policies aimed at improving the quality of preventive lives for people. This involvement is required not only from public officials but also from the private sphere, which should participate in the promotion policies generated by the state. An example is the plan implemented in 2004 by the Ministry of Health, called the "Healthy Living Plan of the State of Chile," which fundamentally seeks to stop risk factors through several measures. These... Continue reading "Article 19, Section 9: Health Rights and Restoration" »

Understanding Grammar: Rules and Their Rationale

Grammar and rules are undoubtedly synonymous in the minds of learners and teachers. The association between them is powerful because the partnership has been fruitful. Rules have served language learning by capturing generalizations about morphosyntactic regularities in a language. Rules also allow material developers to work with "right-sized" chunks of language, helping students deal in an orderly and systematic way with the grammar of the target language. Most language teachers work with rules in some way, even if the rules are not stated in formal metalinguistic terms.

The Rationale Behind Grammar Rules

It is important for learners not only to know the rules, but also to understand why they... Continue reading "Unlocking Grammar: Rules, Reasons, and Effective Language Learning" »
