The cure for a fallacious argument is a better argument, not the suppression of ideas.
You can get into a habit of thought in which you enjoy making fun of all those other people who don't see things as clearly as you do. We have to guard carefully against it.
There are as many atoms in one molecule of DNA as there are stars in a typical galaxy.
I believe our future depends powerfully on how well we understand this cosmos in which we float, like a mote of dust in the morning sky.
We are rare and precious because we are alive, because we can think as well as we can. We are privileged to influence and perhaps control our future. I believe we have an obligation to fight for life on Earth - not just for ourselves, but for all those, humans and others, who came before us, and to whom we are beholden, and for all those who, if we are wise enough, will come after.
Every cell is a triumph of natural selection, and we’re made of trillions of cells. Within us, is a little universe.

I also wish that the Pledge of Allegiance were directed at the Constitution and the Bill of Rights, as it is when the President takes his oath of office, rather than to the flag and the nation
.. Think of the rivers of blood spilled by all those generals and emperors so that in glory and in triumph they could become the 'Momentary' masters of a 'Fraction' of a 'Dot'
The total number of stars in the Universe is larger than all the grains of sand on all the beaches of the planet Earth.
It is the tension between creativity and skepticism that has produced the stunning and unexpected findings of science.
