jars

A jar is a rigid, approximately cylindrical container with a wide mouth or opening. Jars are typically made of glass, ceramic, or plastic. They are used for foods, cosmetics, medications, and chemicals that are relatively thick or viscous: pourable liquids are more often packaged in a bottle. They are also used for items too large to be removed from a narrow neck bottle.

The Journal of Ayn Rand Studies is an academic journal devoted to the study of the philosophy of Ayn Rand. Established in 1999, its founding co-editors were R. W. Bradford, Stephen D. Cox, and New York University scholar Chris Matthew Sciabarra. At present, the editorial board consists of Robert L. Campbell, Stephen D. Cox, Roderick Long, and Chris Matthew Sciabarra. Since 2013, the journal has been published by Pennsylvania State University Press. Although the Objectivist movement of supporters of Rand's philosophy has been criticized as being a cult of personality, the Journal of Ayn Rand Studies often publishes papers by mainstream intellectuals and academics from prestigious universities worldwide that approach Rand's legacy without hagiography.
