So far I have been speaking of theoretical science, which is an attempt to understand the world. Practical science, which is an attempt to change the world, has been important from the first, and has continually increased in importance, until it has almost ousted theoretical science from men's thoug
The root of the matter is a very simple and old fashioned thing... love or compassion. If you feel this, you have a motive for existence, a guide for action, a reason for courage, an imperative necessity for intellectual honesty.
What was exciting in the Victorian Age, would leave a man of franker epoch quite unmoved. The more prudes restrict the permissible degree of sexual appeal, the less is required to make such an appeal effective.
St. Paul introduced an entirely novel view of marriage, that it existed primarily to prevent the sin of fornication. It is just as if one were to maintain that the sole reason for baking bread is to prevent people from stealing cake.
[One] must look into hell before one has any right to speak of heaven.
But if thought is to become the possession of many, not the privilege of the few, we must have done with fear. It is fear that holds men back - fear lest their cherished beliefs should prove delusions, fear lest the institutions by which they live should prove harmful, fear lest they themselves shou
That the world is in a bad shape is undeniable, but there is not the faintest reason in history to suppose that Christianity offers a way out.
A hallucination is a fact, not an error; what is erroneous is a judgment based upon it. Bertrand Russel

Happiness, as is evident, depends partly upon external circumstances and partly upon oneself.
Aristotle and Plato considered Greeks so innately superior to barbarians that slavery is justified so long as the master is Greek and the slave barbarian.
Punctuality is a quality the need of which is bound up with social co-operation.
Written words differ from spoken words in being material structures. A spoken word is a process in the physical world, having an essential time-order; a written word is a series of pieces of matter, having an essential space-order.
When people begin to philosophize they seem to think it necessary to make themselves artificially stupid.
You find as you look around the world that every single bit of progress in humane feeling, every improvement in the criminal law, every step toward the diminution of war, every step toward better treatment of the colored races, or every mitigation of slavery, every moral progress that there has been
