The lecture will focus on the role of perception and visual imagination in human cognition – both in the everyday and scientific sense. A significant part of basic scientific notions is derived from first-hand observation of nature. In addition, a large number of very advanced and abstract scientific theories are based on visual intuitions. The lecture will provide examples of such “picturesque” concepts that have appeared in science since antiquity in areas such as mathematics, physics and philosophy. The presentation is intended to illustrate the thesis that the role of visual competency is not limited to aesthetics or broadly-defined design, but constitutes an important element of human cognition as such.
