Just imagine the silence in the world, if people talked only what they knew

Everyone has the best of feelings towards mankind in general, but not towards the individual man. We'll kill men, but we want to save mankind. And that isn't right, your Reverence. The world will be an evil place as long as people don't believe in other people.

It is a foible of our human nature that when we have an extremely unpleasant experience, it gives us a peculiar satisfaction if it is “the biggest” of its disagreeable kind that has happened since the world began. During a heat wave, for instance, we are very pleased if the papers announce that it is “the highest temperature reached since the year 1881,” and we feel a little resentment towards the year 1881 for having gone us one better. Or if our ears are frozen till all the skin peels off, it fills us with a certain happiness to learn that “it was the hardest frost recorded since 1786.” It is just the same with wars. The war in progress is either the most righteous or the bloodiest, or the most successful, or the longest, since such and such a time; any superlative whatever always affords us the proud satisfaction of having been through something extraordinary and record-breaking.

I had written the sentence, 'You mustn't think that the evolution that gave rise to us was the only evolutionary possibility on this planet. . . . that cultural developments could be shaped through the mediation of another animal species. If the biological conditions were favorable, some civilization not inferior to our own could arise in the depths of the sea. . . . Would it do the same stupid things mankind has done? Would it invite the same historical calamities? What would we say if some animal other than man declared that its education and its numbers gave it the sole right to occupy the entire world and hold sway over all creation?

A garden is never finished. In that sense it is like the human world and all human undertakings.

They all had a thousand good economic and political reasons why they couldn’t stop. I’m not a politician or a businessman; how am I supposed to persuade them about these things. What are we supposed to do; quite likely the world will collapse and disappear under water; but at least that will happen for political and economic reasons we can all understand, at least it will happen with the help of science, technology and public opinion, with human ingenuity of all sorts! Not some cosmic catastrophe but just the same old reasons to do with the struggle for power and money and so on. There’s nothing we can do about that.

Well people are just one species too, aren't they. And it's never stopped them fighting with each other; all the same species and think of all the excuses for war they've used! It hasn't had to be about space to live in, it's been about power, prestige, influence, fame, resources and I don't know what else!
