Mind
The mind is a set of cognitive faculties including consciousness, perception, thinking, judgement, language and memory. It is usually defined as the faculty of an entity's thoughts and consciousness. It holds the power of imagination, recognition, and appreciation, and is responsible for processing feelings and emotions, resulting in attitudes and actions.
Technology
Technology ("science of craft", from Greek τέχνη, techne, "art, skill, cunning of hand"; and -λογία, -logia) is first robustly defined by Jacob Bigelow in 1829 as: "...principles, processes, and nomenclatures of the more conspicuous arts, particularly those which involve applications of science, and which may be considered useful, by promoting the benefit of society, together with the emolument [compensation ] of those who pursue them" .
Mind
If you think about it, the inside of your own mind is the only thing you can be sure of.

Mind
Man's mind a mirror is of heavenly sights,
A brief wherein all marvels summèd lie,
Of fairest forms and sweetest shapes the store,
Most graceful all, yet thought may grace them more.
Robert Southwell, Content and Rich (Look Home).
Technology
There is a demon in technology. It was put there by man and man will have to exorcise it before technological civilization can achieve the eighteenth-century ideal of humane civilized life.
René Dubos, A God Within (1972), 216.
