Whenever we hear an opinion and believe it, we make an agreement, and it becomes part of our belief system.

I want to oppose the idea that the school has to teach directly that special knowledge and those accomplishments which one has to use later directly in life. The demands of life are much too manifold to let such a specialized training in school appear possible [...] The development of general ability for independent thinking and judgement should always be placed foremost.

To some people critical thinking means you mustn't be critical of them only others

The essence of the independent mind lies not in what it thinks, but in how it thinks.

People tend to say "I like independent thinkers but they must think what i want them to think independently

To some people independent though is heresy and critical thought blasphemy
