Famous Steven Weinberg Quotes

“Even though their arguments did not invoke religion, I think we all know what's behind these arguments. They're trying to protect religious beliefs from contradiction by science. They used to do it by prohibiting teachers from teaching evolution at all; then they wanted to teach intelligent design as an alternative theory; now they want the supposed "weaknesses" in evolution pointed out. But it's all the same program - it's all an attempt to let religious ideas determine what is taught in science courses.”

“Alas, Islam turned against science in the twelfth century. The most influential figure was the philosopher Abu Hamid al-Ghazzali, who argued in The Incoherence of the Philosophers against the very idea of laws of nature, on the ground that any such laws would put God's hands in chains. According to al-Ghazzali, a piece of cotton placed in a flame does not darken and smoulder because of the heat, but because God wants it to darken and smoulder. After al-Ghazzali, there was no more science worth mentioning in Islamic countries.”

“We have simply arrived too late in the history of the universe to see this primordial simplicity easily... But although the symmetries are hidden from us, we can sense that they are latent in nature, governing everything about us. That's the most exciting idea I know: that nature is much simpler than it looks. Nothing makes me more hopeful that our generation of human beings may actually hold the key to the universe in our hands - that perhaps in our lifetimes we may be able to tell why all of what we see in this immense universe of galaxies and particles is logically inevitable.”

“I now want to tell three stories about advances in twentieth-century physics. A curious fact emerges in these tales: time and again physicists have been guided by their sense of beauty not only in developing new theories but even in judging the validity of physical theories once they are developed. Simplicity is part of what I mean by beauty, but it is a simplicity of ideas, not simplicity of a mechanical sort that can be measured by counting equations or symbols.”
