The wheels and springs of man are all set to the hypothesis of the permanence of nature. We are not built like a ship to be tossed, but like a house to stand.
It seldom happens that a man changes his life through his habitual reasoning. No matter how fully he may sense the new plans and aims revealed to him by reason, he continues to plod along in old paths until his life becomes frustrating and unbearable-he finally makes the change only when his usual life can no longer be tolerated.
When we least expect it, life sets us a challenge to test our courage and willingness to change; at such a moment, there is no point in pretending that nothing has happened or in saying that we are not yet ready. The challenge will not wait. Life does not look back. A week is more than enough time for us to decide whether or not to accept our destiny.
Don't let yourself be weighed down by what other people think, because in a few years, in a few decades, or in a few centuries, that way of thinking will have changed. Live now what others will only live in the future.
Here's the truth: even if countries like the United States curb our emissions, if growing countries like India - with soaring energy needs - don't also embrace cleaner fuels, then we don't stand a chance against climate change.
It is the free alone which never changes, and the unchangeable alone which is free; for change is produced by something exterior to a thing, or within itself, which is more powerful than the surroundings.
