Metaphysics: Key Concepts and Philosophical Methods
Topics of Metaphysics
The word “metaphysics” is a collection invented to designate the works of Aristotle that dealt with the first principles of all sciences:
- Science: Decides the object of study more precisely, leading to a perfect, precise language. The strength of scientific evidence is very powerful, so that no physicist discusses the theories of relativity or quantum mechanics.
- Philosophy: Does not have the strength of scientific evidence. It seems that neither philosophers nor scientists agree

Tectonic Plate Boundaries and Their Effects
Destructive Margins (Convergent Boundaries)
Destructive plate boundaries, or convergent boundaries, are areas where volcanic activity produces new oceanic lithosphere. These areas of lithosphere creation are called constructive margins. At these ridges, huge fracture zones exist where basaltic magma exits under pressure. These zones are often patchy and unstable. As the extension of the seafloor originates from each zone, a contraction occurs when two sections

**1. What is the Intrinsic Differential Note of Commercial Versus Civil Contracts?**
In the commercial sphere, obligations are objectified, whereas in civil law, they are subjective. Other hallmarks include:
- Fate of the term of compliance: Commercial law prohibits grace periods tolerated in civil law.
- Certainty on the recoverability of pure obligations: Civil contracts are enforceable from the moment they are incurred. Commercial contracts often operate on credit.
- Constitution of arrears: Obligations
Cognitive Impairment in Dementia: Symptoms and Diagnosis
Cognitive Impairment in Dementia
This article discusses the most relevant aspects of some of the more frequent cognitive symptoms of dementia. We review the superior functions that are altered during the evolutionary process of dementia, taking Alzheimer’s disease with amnesic syndrome-aphasic-apraxic-agnostic as a paradigm. Then, we analyze the clinical differences between the most common dementias: cortical and subcortical.
Introduction
A few years ago, the concept of dementia was always related
Citizenship, Democracy, and Globalization: Key Concepts
The Political Experience of Greece and its Influence
The political experience of Greece, as analyzed by Aristotle, had a decisive influence on Western political thought. The citizen is defined as a function of the city-state system. Not every inhabitant of the city has the condition of a citizen; women and slaves do not. Residence in the city does not automatically confer citizenship, although there are residents with certain rights who are not citizens. Children and the elderly are considered imperfect

The Decomposition of the System (1917-1923)
4.1. Political Decay
The regime of the Restoration entered a gradual decay due to the desire for political renewal, weak dynastic leaders, and a heterogeneous and weak opposition.
The dynastic parties, without clear leaders, were split into groups headed by different politicians, so it was not possible to gather a sufficient parliamentary majority to form stable governments. From 1917, they often turned to governments of concentration as a solution. The most

London, 1884
In 1884 London, a doctor named Lord Frederick Treves was walking down the street when he found a painting in a shop window.

Ferdinand VII: Absolutism, Liberalism, and the Loss of Spanish America
The Restoration of Absolutism
Under the Treaty of Valençay (1813), Ferdinand VII returned to Spain. Supporters of absolutism urged him to restore the old order, believing the Liberals were weak.

Ferdinand VII disappointed liberals and reformers by nullifying the Constitution of Cadiz (1812)
