A word cloud is an image made of words that together resemble a cloudy shape.
The size of a word shows how important it is e.g. how often it appears in a text - its frequency.

People typically use word clouds to easily produce a summary of large documents (reports, speeches), to create art on a topic (gifts, displays) or to visualise data (tables, surveys).

En webdianoia encontrarás materiales para el estudio de la historia de la filosofía. Es una web pensada para estudiantes de Secundaria, especialmente del último curso, y podrás encontrar en ella la exposición de las principales líneas del pensamiento de los autores y autoras tratados, así como su biografía, la relación de sus obras y la exposición del contexto histórico en que vivieron. Pero hay también otras secciones que pueden ser de tu interés, como un glosario filosófico con los términos más comunes en filosofía, una sección de ejercicios, que te podrán servir de referencia para controlar tu aprendizaje y fijar tus conocimientos; o sencillas orientaciones sobre cómo estudiar filosofía. Y otras pocas cosas más que quizá sean de tu interés y podrás ir descubriendo a tu aire, si decides permanecer en la página o visitarnos de nuevo en el futuro. (2023)

La inmortalidad del alma en el "Fedón" de Platón

- Cebes, interrumpiendo a Sócrates, le dijo: lo que dices es un resultado necesario de otro principio que te he oído muchas veces sentar como cierto, a saber: que nuestra ciencia no es más que una reminiscencia. Si este principio es verdadero, es de toda necesidad que hayamos aprendido en otro tiempo las cosas de que nos acordamos en este; y esto es imposible, si nuestra alma no existe antes de aparecer bajo esta forma humana. Esta es una nueva prueba de que nuestra alma es inmortal.
- Simmias, interrumpiendo a Cebes, le dijo: ¿cómo se puede demostrar este principio? Recuérdamelo, porque en este momento no caigo en ello.
- Hay una demostración muy preciosa, respondió Cebes, y es que todos los hombres, si se les interroga bien, todo lo encuentran sin salir de sí mismos, cosa que no podría suceder, si en sí mismos no tuvieran las luces de la recta razón. En prueba de ello, no hay más que ponerles delante figuras de geometría u otras cosas de la misma naturaleza, y se ve patentemente esta verdad.
- Si no te das por convencido con esta experiencia, Simmias, replicó Sócrates, mira si por este otro camino asientes a nuestro parecer. ¿Tienes dificultad en creer que aprender no es más que acordarse?
- No mucha, respondió Simmias; pero lo que precisamente quiero es llegar al fondo de ese recuerdo de que hablamos; y aunque gracias a lo que ha dicho Cebes, hago alguna memoria y comienzo a creer, no me impide esto el escuchar con gusto las pruebas que tú quieres darnos.
- Helas aquí, replicó Sócrates. (...)

La naturaleza de la ciencia según Aristóteles

Todos los hombres tienen naturalmente el deseo de saber. El placer que nos causa las percepciones de nuestros sentidos es una prueba de esta verdad. Nos agradan por sí mismas, independientemente de su utilidad, sobre todo las de la vista. En efecto, no sólo cuando tenemos intención de obrar, sino hasta cuando ningún objeto práctico nos proponemos, preferimos, por decirlo así, el conocimiento visible a todos los demás conocimientos que nos dan los demás sentidos. Y la razón es que la vista, mejor que los otros sentidos, nos da a conocer los objetos, y nos descubre entre ellos gran número de diferencias.

Los animales reciben de la naturaleza la facultad de conocer por los sentidos. Pero este conocimiento en unos no produce la memoria; al paso que en otros la produce. Y así los primeros son simplemente inteligentes; y los otros son más capaces de aprender que los que no tienen la facultad de acordarse. La inteligencia, sin la capacidad de aprender, es patrimonio de los que no tienen la facultad de percibir los sonidos, por ejemplo, la abeja y los demás animales que puedan hallarse en el mismo caso. La capacidad de aprender se encuentra en todos aquellos que reúnen a la memoria el sentido del oído. Mientras que los demás animales viven reducidos a las impresiones sensibles o a los recuerdos, y apenas se elevan a la experiencia, el género humano tiene, para conducirse, el arte y el razonamiento.

La filosofía de Platón constituye el primer libro educativo en formato multi-táctil (multi-touch) y lengua castellana que publica la editorial Manuscritos, novedoso formato que aúna hipertexto, vídeo, audio, recursos 3D e interactivos que amenizan y facilitan el aprendizaje.

Para dar a conocer las posibilidades de este formato aplicado a la enseñanza de la Historia de la filosofía, hemos elegido al filósofo ateniense Platón, el más leído y comentado del mundo, que ya nos advirtió de las deficiencias del lenguaje escrito frente a la trasmisión oral del conocimiento, optando él por la forma más dialógica de comunicación: el diálogo. A buen seguro, nuestro filósofo hubiera aprovechado todos estos recursos en la Academia.
se divide en siete grandes apartados: biografía, metafísica, teoría del conocimiento, cosmología, antropología, ética y política. En cada uno de ellos encontraremos un desarrollo pormenorizado de cada ámbito del saber, acompañado por textos originales del filósofo, vídeos, esquemas ampliables, glosario, ejercicios y pruebas de evaluación muy útiles para los alumnos que cursan 2º de Bachillerato. Cada unidad se cierra con un vídeo de Fedro, personaje que nos resume los contenidos de cada capítulo.

Este libro se irá actualizando con nuevos recursos que consideremos útiles y que podrán ser sugeridos por profesores y alumnos, adhiriéndose así a esa vocación mayéutica que el propio Platón practicó con genial maestría.

A APH partilha na sua página links para sítios da internet onde podem ser encontrados materiais úteis para o ensino aprendizagem da nova disciplina.

HISTÓRIA, CULTURAS E DEMOCRACIA (HCD) é uma disciplina anual de opção destinada aos alunos dos cursos científico-humanísticos de Ciências e Tecnologias, de Ciências Socioeconómicas e de Artes Visuais do Ensino Secundário; enquadra-se nas opções de oferta de escola e pretende contribuir, recorrendo às metodologias e instrumentos da História, para o desenvolvimento de competências de reflexão crítica, consistente e autónoma sobre a nossa contemporaneidade. Dadas as suas características, deve ser exclusivamente lecionada por docentes dos Grupos 200 e 400.

HCD pretende contribuir para a consecução do Perfil dos Alunos à Saída da Escolaridade Obrigatória, recorrendo à multiperspetiva e a comparações entre realidades espácio-temporais distintas, possibilitando que o aluno desenvolva a compreensão do mundo em que vive e uma consciência histórica que lhe permite assumir uma posição informada, crítica e participativa na construção da sua identidade individual e coletiva, num quadro de referência humanista e democrático. Os quatro temas propostos - A HISTÓRIA FAZ-SE COM CRITÉRIO, "GLOCAL" E CONSCIÊNCIA PATRIMONIAL, PASSADOS DOLOROSOS NA HISTÓRIA, HISTÓRIA E TEMPO PRESENTE - foram estruturados em torno de três eixos organizadores: construção do conhecimento histórico com base em metodologias específicas; compreensão do mundo atual a partir da exploração do local, do regional e do global; problematização de temas da História recente, integrando as relações passado-presente, pensados em articulação com princípios, visão e valores identificados no Perfil dos Alunos À Saída da Escolaridade Obrigatória.
