Some people wave their dogmatic thinking until their own reason is entangled.
— Samuel Johnson

Nothing is more dangerous than a dogmatic worldview - nothing more constraining, more blinding to innovation, more destructive of openness to novelty.
Stephen Jay Gould dogmatic quote

Dogma is actually the only thing that cannot be separated from education. It IS education. A teacher who is not dogmatic is simply a teacher who is not teaching. There are no uneducated people; only most people are educated wrong. The true task of culture today is not a task of expansion, but of selection-and rejection. The educationist must find a creed and teach it.
— G. K. Chesterton

If you would inform, a positive and dogmatic manner in advancing your sentiments may provoke contradiction and prevent a candid attention. If you wish information and improvement from the knowledge of others, and yet at the same time express yourself as firmly fixed in your present opinions, modest, sensible men, who do not love disputation, will probably leave you undisturbed in the possession of your error.
— Frank Crane

When distant and unfamiliar and complex things are communicated to great masses of people, the truth suffers a considerable and often a radical distortion. The complex is made over into the simple, the hypothetical into the dogmatic, and the relative into an absolute.
— Walter Lippmann
