Counting the Omer reminds us that things that are worthwhile and meaningful in life don’t happen at lightening speed and require focus. In fact, it is quite the opposite. A famous mishna from Berachot, for example, teaches us that early mystics would prepare for an hour to pray, then would pray, and would spend an hour winding down afterward.

Better a bad press than a good epitaph.

Today, for the mass of humanity, science and technology embody ‘miracle, mystery, and authority’. Science promises that the most ancient human fantasies will at last be realized. Sickness and ageing will be abolished; scarcity and poverty will be no more; the species will become immortal. Like Christianity in the past, the modern cult of science lives on the hope of miracles. But to think that science can transform the human lot is to believe in magic. Time retorts to the illusions of humanism with the reality: frail, deranged, undelivered humanity. Even as it enables poverty to be diminished and sickness to be alleviated, science will be used to refine tyranny and perfect the art of war.

So you think that money is the root of all evil?” said Francisco d’Anconia. “Have you ever asked what is the root of money? Money is a tool of exchange, which can’t exist unless there are goods produced and men able to produce them. Money is the material shape of the principle that men who wish to deal with one another must deal by trade and give value for value. Money is not the tool of the moochers, who claim your product by tears, or of the looters, who take it from you by force. Money is made possible only by the men who produce. Is this what you consider evil?

Suponhamos que alguém fosse consistentemente bem sucedido ao predizer eventos de uma certa espécie, eventos, por assim dizer, que não são ordinariamente considerados predizíveis, como o resultado de uma loteria. Se sua série de sucessos fosse suficientemente impressionante poderíamos muito bem chegar a dizer que ele sabia quais números iriam ser sorteados, embora não chegasse a essa conclusão por algum método racional, ou mesmo por qualquer método. Podíamos dizer que ele sabia isso por intuição, mas isto seria afirmar que sabia mas que não podia dizer como. Da mesma maneira, se alguém fosse consistentemtne bem sucedido ao ler as mentes dos outros sem ter qualquer tipo usual de evidência, poderíamos dizer que conhecia essas coisas telepaticamente. Mas na falta de qualquer explicação adicional poder-se-ia dizer apenas que as conhecia, mas não pelos meios ordinarios. Palavras como “intuição” e “telepatia” servem apenas para disfarçar o fato de que nenhuma explicação foi encontrada. … Devemos lhe conceder o direito de estar certo, simplesmente na base do seu êxito.

The only freedom which deserves the name is that of pursuing our own good in our own way, so long as we do not attempt to deprive others of theirs, or impede their efforts to obtain it. Each is the proper guardian of his own health, whether bodily, or mental or spiritual. Mankind are greater gainers by suffering each other to live as seems good to themselves, than by compelling each to live as seems good to the rest.

I think this flavour of logic refuted by the world makes the paradox rather fascinating. The logician goes pathetically through the motions that have always worked the spell before, but somehow the monster, Reality, has missed the point and advances still.

Guardai-vos de fazer as vossas boas obras diante dos homens, para vos tornardes notados por eles. De contrário, não tereis nenhuma recompensa do vosso Pai que está nos Céus. Quando, pois, deres esmola, não toquem trombeta diante de ti, como fazem os hipócritas, nas sinagogas e nas ruas, a fim de serem louvados pelos homens.

Falsehood has an infinity of combinations, but truth has only one mode of being.
