"The (Iranian) government failed to quarantine and disinfect all cities (from SARS-CoV-2) before it was too late. We must comply with the health rules to protect from the (COVID-19) disease."

"Every knowledge in which the reason is involved is not a rational knowledge. It means that any knowledge because the reason is involved in it cannot be considered as a rational knowledge. In a rational knowledge, it is necessary that in addition to the existence of reason, the judgment of reason about the thing that is to be known should be consistent with the reason and be rational. It is also necessary that the result of this knowledge be rational so that we consider that knowledge a rational knowledge (the necessary and sufficient conditions for rational knowledge)."

"The knowledge of anything, since all things have causes, is not acquired or complete unless it is known by its causes. Therefore in medicine we ought to know the causes of sickness and health. And because health and sickness and their causes are sometimes manifest, and sometimes hidden and not to be comprehended except by the study of symptoms, we must also study the symptoms of health and disease. Now it is established in the sciences that no knowledge is acquired save through the study of its causes and beginnings, if it has had causes and beginnings; nor completed except by knowledge of its accidents and accompanying essentials. Of these causes there are four kinds: material, efficient, formal, and final."

"The world is divided into men who have wit and no religion and men who have religion and no wit."

"I [prefer] a short life with width to a narrow one with length."

"Medicine considers the human body as to the means by which it is cured and by which it is driven away from health."
