INTERNAL AND EXTERNAL LOGIC In an essential way I make use of Fregeâs and Vasilevâs ideas. N. A. Vasilev distinguished two levels in a logic. The abstract (external) logic depends on gnoeologic assumptions while the empirical (internal) part of logic depends on ontological ones. Vasilev did not change the external logic but he did change the internal one. His system can be viewed as a non-standard syllogistics based on classical propositional logic (see [5], [6]).
The difference between an external stimulus and an  internal stimulus is that an external  stimulus is a stimulus that comes from  outside an organism.But an internal  st â¦ umulus is a stimulus that comes from  inside an organism.n example of an external stimulus is a painful prick (and any other stimulus that happens OUT side the organism). The organism could respond by pulling away from the pain ca â¦ used by the stimuli.
