Seduction

Seduction is the process of deliberately enticing a person, to lead astray, as from duty, rectitude, or the like; to corrupt, to persuade or induce to engage in sexual behaviour. The word seduction stems from Latin and means literally "to lead astray". As a result, the term may have a positive or negative connotation. Famous seducers from history or legend include Lilith, Giacomo Casanova and the fictional character Don Juan. Seduction as a phenomenon is not the subject of scientific interest, although similar, more specific terms like short-term mating, casual sex or mating strategies are used in evolutionary psychology. The Internet enabled the existence of a seduction community which is based on pseudoscientific discourse on seduction.

Seduction, seen negatively, involves temptation and enticement, often sexual in nature, to lead someone astray into a behavioral choice they would not have made if they were not in a state of sexual arousal. Seen positively, seduction is a synonym for the act of charming someone — male or female — by an appeal to the senses, often with the goal of reducing unfounded fears and leading to their "sexual emancipation" Some sides in contemporary academic debate state that the morality of seduction depends on the long-term impacts on the individuals concerned, rather than the act itself, and may not necessarily carry the negative connotations expressed in dictionary definitions.

Darkness

Darkness, the polar opposite to brightness, is understood to be an absence of visible light. It is also the appearance of black in a colored space.

Humans are unable to distinguish color when either light or darkness predominate. In conditions of insufficient light, perception is achromatic and ultimately, black.

The emotional response to darkness has generated metaphorical usages of the term in many cultures.

Scientific

Perception

The perception of darkness differs from the mere absence of light due to the effects of after images on perception. In perceiving, the eye is active, and that part of the retina that is unstimulated produces a complementary afterimage.

Physics

In terms of physics, an object is said to be dark when it absorbs photons, causing it to appear dim compared to other objects. For example, a matte black paint does not reflect much visible light and appears dark, whereas white paint reflects much light and appears bright. For more information see color.

Light cannot be absorbed without limit. According to the principle of the conservation of Energy, energy cannot be created or destroyed; it can only be converted from one type to another. Consequently, most objects that absorb visible light reemit it as heat. So, although an object may appear dark, it is likely bright at a frequency that humans cannot perceive. For more information see thermodynamics.
