Reason like science, grows by way of mutual criticism; the only possible way of planning its growth is to develop those institutions that safeguard. the freedom of thought
ideas grows new-ideas
What really makes science grow is new ideas, including false ideas.

Genuine philosophical problems are always rooted outside philosophy and they die if these roots decay.

Simple statements are to be prized more highly than less simple ones because they tell us more; because their empirical content is greater; and because they are better testable.
freedom government office
It is wrong to ask who will rule. The ability to vote a bad government out of office is enough. That is democracy.
taken atheism consideration
A system is empirical or scientific only if it is capable of being tested by experience. These considerations suggest that not the verifiability but the falsifiability of a system is to be taken as a criterion of demarcation... It must be possible for an empirical or scientific system to be refuted by experience.
numbers history kind
There is no history of mankind, there is only an indefinite number of histories of all kinds of aspects of human life.

All things living are in search of a better world .

[The aim of science is] to explain what so far has taken to be an explicans, such as a law of nature. The task of empirical science constantly renews itself. We may go on forever, proceeding to explanations of a higher and higher universality...
law belief natural
Our belief in any particular natural law cannot have a safer basis than our unsuccessful critical attempts to refute it.

Propose theories which can be criticized. Think about possible decisive falsifying experiments-crucial experiments. But do not give up your theories too easily-not, at any rate, before you have critically examined your criticism.
math talking mathematical-logic
We never know what we are talking about.
analysis logical stage
The initial stage, the act of conceiving or inventing a theory, seems to me neither to call for logical analysis nor to be susceptible of it.
