Ilusões Populares

Os homens, já se disse muito bem, pensam em bandos; e se verá que eles enlouquecem em bandos, ao passo que só recobram a lucidez lentamente e um a um.

A arte de se ter razão

José Colucci Jr.
Mais doído do que ouvir um oponente defender mal a idéia que combatemos é ouvir um aliado defender mal a idéia com a qual simpatizamos. Felizmente para a simetria dos debates, as patologias do raciocínio não tem preferência partidária, profissional, de gênero, credo religioso ou classe social. Vindas da direita ou da esquerda, de políticos ou professores, de religiosos ou ateus, as agressões à lógica são sempre golpes baixos.

Freqüentar a escola ajuda, mas não muito. A educação tradicional não imuniza contra as falácias e conclusões pouco científicas. Para isso é preciso treinamento no chamado "pensamento crítico" – o exercício de formar crenças a partir de observações e decisões racionais sobre a realidade.

"MILAGRE DO SANGUE"

Mistura à base de ferro, cálcio, água e sal de cozinha explicaria o mistério de são Genaro

Químicos questionam sangue de santo
JEAN-JACQUES BOZONNET
DO "LE MONDE", EM ROMA

"Dissolva 25 gramas de cloreto de ferro em cem mililitros de água, acrescente dez gramas de carbonato de cálcio. A reação química fará a solução ficar marrom escura. Passe a solução para um recipiente de gargalo fino, acrescente sal de cozinha, agite e deixe descansar por duas horas." Essa é a receita sacrílega proposta na internet aos interessados em reproduzir em casa o sangue de são Genaro, o santo cujo 1.700º aniversário de morte, por decapitação, a cidade de Nápoles comemorou no último dia 19.

O gel, cujo modo de fabricação figura no site do Comitê Italiano para o Controle dos Fenômenos Paranormais (Cicap), se liquefaz quando é ligeiramente sacudido. "O processo pode ser reproduzido à vontade", diz o site.

Para a astrofísica Margherita Hack, do Cicap, não é preciso procurar mais longe a explicação do suposto "milagre do sangue", pelo qual o sangue seco do santo fica líquido três vezes por ano na catedral de Nápoles -no primeiro domingo de maio, a cada 19 de setembro e a cada 16 de dezembro -, em um fenômeno descrito pela igreja como "acontecimento prodigioso".

Radionics

Radionics is a form of energy medicine created by Dr. Albert Abrams (1863-1924), the "dean of twentieth century charlatans."* Abrams claimed that he was able to detect distinct energies or vibrations (radiation) being emitted from healthy and diseased tissue in all living things. He invented devices that allegedly could measure this energy (vibration, radiation) and he created a system for evaluating vibrations as signs of health or disease.
