Answer something that is related to something else
Originally a mathematical term, the Greek word for analogy means "proportion" and was borrowed by philosophers. to refer to the relationship between concepts of things that are partly the same and partly different. It took on special importance in the concept of analogy of being (Latin: analogia entis). The analogy of faith (analogia fidei) must not be confused with this more philosophic concept..
It means something so insignificant that it is not noticeable.
As a , analogy means a certain similarity mixed with difference. This similarity may be founded entirely or chiefly upon a conception of the mind; in this sense we say that there is analogy between the light of the sun and the light of the mind, between a lion and a man, between an organism and . This kind of analogy is the source of metaphor. The similarity may be founded on the real existence of similar properties in objects of different species, genera, or classes; those organs, for instance, are analogous, which, belonging to beings of different species or genera, and differing in structure, fulfil the same physiological functions or have the same connections. As a process of reasoning, analogy consists in concluding from some analogical properties or similarity under certain aspects to other analogical properties or similarity under other aspects. It was by such a process that Franklin passed from the analogy between the effects of lightning and the effects of electricity to the identity of their cause; Cuvier, from the analogy between certain organs of fossils and these organs in actual species to the analogy of the whole organism; that we infer from the analogy between the organs and external actions of animals and our own, the existence of consciousness in them. Analogical reasoning is a combination of and based on the principle that "analogical properties considered as similar involve similar consequences". It is evident that analogical reasoning, as to its value, depends on the value of the analogical on which it rests. Based on a mere conception of the mind, it may suggest, but it does not prove; it cannot give conclusions, but only comparisons. Based on real properties, it is more or less conclusive according to the number and significance of the similar properties and according to the fewness and insignificance of the dissimilar properties. From a strictly point of view, analogical reasoning can furnish only probable conclusions and hypotheses. Such is the case for most of the theories in physical and natural , which remain hypothetical so long as they are merely the result of analogy and have not been verified directly or indirectly.
If you have an analog watch, it tells the time with hands that sweep arounda dial: the position of the hands is a of the time. Howmuch the hands move is directly related to what time it is. So if thehour hand sweeps across two segments of the dial, it's showing thattwice as much time has elapsed compared to if it had moved only onesegment. That sounds incredibly obvious, but it's much more subtlethan it first seems. The point is that the hand's movements over thedial are a way of passing time. It's not the samething as time itself: it's a representation or an of time. The same is true when you measure something with a ruler. Ifyou measure the length of your finger and mark it on the surface of awooden ruler, that little strip of or plastic you're looking at(a small segment of the ruler) is the same length as your finger. Itisn't your finger, of course—it's a representation of your finger:another analogy. That's really what the term analog means.
