" "the heart of science is an essential balance between two seemingly contradictory attitudes — an openness to new ideas, no matter how bizarre or counterintuitive, and the most ruthlessly skeptical scrutiny of all ideas, old and new.

About Carl Sagan
Carl Edward Sagan (9 November 1934 – 20 December 1996) was an American astronomer, planetary scientist, cosmologist, astrophysicist, astrobiologist, author, and science communicator. His best known scientific contribution is research on extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by radiation. Sagan assembled the first physical messages sent into space, the Pioneer plaque and the Voyager Golden Record, universal messages that could potentially be understood by any extraterrestrial intelligence that might find them. Sagan argued the hypothesis, accepted since, that the high surface temperatures of Venus can be attributed to, and calculated using, the greenhouse effect. He testified to the US Congress in 1985 that the greenhouse effect will change the earth's climate system.

Additional quotes by Carl Sagan
«قد يجادل أحد، بأن الدجلنة يجري اعتناقها على نحو يتناسب طرديًا وبدقة مع عدم فهم العلم الحقيقي فإذا كنت لم تسمع عن العلم مطلقًا (ناهيك عن الطريقة التي يسير بها)، فستكون بالكاد قادرًا على الوعي بأنك تعتنق الدجلنة. وما تفعله ببساطة هو التفكير بإحدى الطرق التي يُفكر بها البشر دائمًا. فالأديان غالبًا ما تكون بمثابة الحضانات التي تحميها الدولة كي تترعرع داخلها الدجلنة، رغم عدم وجود سبب يضطر الدين إلى لعب هذا الدور. فهذا الدور إلى حد ما شيء اصطنعه الإنسان منذ عصور موغلة في القدم. ففي بعض البلاد، يعتقد الجميع، تقريبًا، في التنجيم والمعرفة المسبقة بالأحداث، بما في ذلك زعماء الحكومات. غير أن هذا لم يقحم على عقولهم ببساطة بفعل الدين، وإنما هذا الإيمان بالتنجيم مستمد من الثقافة المحيطة التي يستريح فيها الجميع إلى هذه الممارسات، والشواهد التي تؤكد ذلك توجد في كل مكان.»
St. Anselm argued that since we can imagine a perfect being, he must exist—because he would not be perfect without the added perfection of existence. This so-called ontological argument was more or less promptly attacked on two grounds: (1) Can we imagine a completely perfect being? (2) Is it obvious that perfection is augmented by existence? To the modern ear such pious arguments seem to be about words and definitions rather than about external reality.
