Of course you know the movie, just by cultural assimilation if not by having seen it. There’s this young elephant, Dumbo, who has laughably big ears and has been pitiably separated from his mom. He’s aided by a friendly talking mouse[ii] into translating those otherwise hapless ears into the power of flight, which he eventually uses to rescue his mom and live happily ever after. The way the wily mouse gets Dumbo to believe that he could fly is to give (...) him a “magic feather” which, held in his trunk, demonstrably imparts the gift of flight. Naturally the mouse believes throughout all this that Dumbo can fly anyway, but he also knows that Dumbo needs the feather as a confidence-builder to do so. At the critical juncture of the tale Dumbo loses the feather after being pushed off a precipice, and he thus plummets perilously towards earth—only to find at the last moment that he can indeed fly on his own.

Teyyar eschatology, as a doctrine of the ultimate destiny of mankind, is deeply rooted in the concept of the ultimate goal, which is regarded as a true result, though it emerges as a tool designed to fill some of the emptiness created by humanity in the course of natural science practice. Teillard felt that the deplorable state of modern mankind was the result of his neglect of eschatology, his inability to adapt to the needs of his activities, and his lack (...) of courage in further design. "A lighter skyscraper of hope is being constructed," G. Grespi notes. The belief that the Earth is exhausting its limited resources necessarily leads to the thought of the destruction of the Earth.

The policy adopted by the Twenty-fifth Congress of the CPSU on raising the quality of work and the effectiveness of social production means that work must be more highly organized and disciplined and that initiative and creative searching must be fostered.
