It seems pretty simple…if you do something that hurts you, you probably won’t do it again. Whether it be physical or emotional pain, these things have a large impact on how we act and what we do. Sensory data, or sensedata, is what compels us to perceive. Without this sensory perception, how can we tell if an apple is an apple, or that the stove top is hot? Both give off properties which we must register in order to make judgment on what it is. Both Hume and Descartes talked about this sensedata. The Cartesian aspects are more skeptical and not as involved. Hume was more empirical with his ways of thinking. He stated that fiction was rooted in pure imagination, while belief came from imagination and emotion.
From the Hume reading; “When a child has felt the sensation of pain from touching the flame of a candle, he will be careful not to put his hand near any candle; but will expect a similar effect from a cause, which is similar in its sensible qualities and appearance.” This quote explains sensory data the Humiean way; it is very realistic and empirical. Basically, a child doesn’t learn through reasoning, but through the conditioning of custom. It seems so simple, but is it?
