| 18609 | Psychologists use 'induction' as generalising a property from one category to another [Machery] |
| Full Idea: Typically, psychologists use 'induction' to refer to the capacity to generalise a property from a category (the source) to another category (the target). | |
| From: Edouard Machery (Doing Without Concepts [2009], 7.1.1) | |
| A reaction: This is because psychologists are interested in the ongoing activities of thought. Philosophers step back a bit, to ask how the whole thing could get started. Philosophical induction has to start with individuals and single observations. |
| 18610 | 'Ampliative' induction infers that all members of a category have a feature found in some of them [Machery] |
| Full Idea: Induction is 'ampliative' when it infers that all or most members of a category possess a property from the fact that some of its members have this property. | |
| From: Edouard Machery (Doing Without Concepts [2009], 7.1.1) | |
| A reaction: This sounds like a simple step in reasoning, but actually it is more like explanation, and will involve overall coherence and probability, rather than a direct conclusion. This invites sceptical questions. The last one observed may be the exception. |
