“Keep in mind that right and wrong are not matters of opinion. They are principles we must discover and apply. They are laws of biology for intelligent species”

“All, too, will bear in mind this sacred principle, that though the will of the majority is in all cases to prevail, that will to be rightful must be reasonable; that the minority possess their equal rights, which equal law must protect, and to violate would be oppression. ”

“I am not an advocate for frequent changes in laws and Constitutions. But laws and institutions must go hand in hand with the progress of the human mind. As that becomes more developed, more enlightened, as new discoveries are made, new truths discovered and manners and opinions change, with the change of circumstances, institutions must advance also to keep pace with the times. We might as well require a man to wear still the coat which fitted him when a boy as civilized society to remain ever under the regimen of their barbarous ancestors.”

“In the beginning, there was physics. "Physics" describes how matter, energy, space, and time behave and interact with one another. The interplay of these characters in our cosmic drama underlies all biological and chemical phenomena. Hence everything fundamental and familiar to us earthlings begins with, and rests upon, the laws of physics. When we apply these laws to astronomical settings, we deal with physics writ large, which we call astrophysics.”

“The Laws Of God, The Laws Of ManThe laws of God, the laws of man,He may keep that will and can;Now I: let God and man decree Laws for themselves and not for me;And if my ways are not as theirsLet them mind their own affairs. Their deeds I judge and much condemn,Yet when did I make laws for them?Please yourselves, say I, and theyNeed only look the other way.But no, they will not; they must stillWrest their neighbour to their will,And make me dance as they desireWith jail and gallows and hell-fire.And how am I to face the oddsOf man’s bedevilment and God’s?I, a stranger and afraidIn a world I never made.They will be master, right or wrong;Though both are foolish, both are strong, And since, my soul, we cannot fly To Saturn or Mercury,Keep we must, if keep we can,These foreign laws of God and man.”

“The remarkable feature of physical laws is that they apply everywhere, whether or not you choose to believe in them. After the laws of physics, everything else is opinion.”
