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.
In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
True compassion is not just an emotional response, but a firm commitment founded on reason. Therefore, a truly compassionate attitude toward others does not change, even if they behave negatively. Through universal altruism, you develop a feeling of responsibility for others: the wish to help them actively overcome their problems.
The recurrence of a phenomenon like Edison is not very likely. The profound change of conditions and the ever increasing necessity of theoretical training would seem to make it impossible. He will occupy a unique and exalted position in the history of his native land, which might well be proud of his great genius and undying achievements in the interest of humanity.
Revolution is not something fixed in ideology, nor is it something fashioned to a particular decade. It is a perpetual process embedded in the human spirit.
This world is not for aye, nor 'tis not strange
That even our loves should with our fortunes change,
For 'tis a question left us yet to prove,
Whether love lead fortune, or else fortune love.
The nearer a conception comes towards finality, the nearer does the dynamic relation, out of which this concept has arisen, draw to a close. To know is to lose.
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.
Unless we change our ways and our direction, our greatness as a nation will soon be a footnote in the history books, a distant memory of an offshore island, lost in the mist of time like Camelot, remembered kindly for its noble past.
