Document Summary
If you miss the test, you need a valid doctor"s note. Descartes" view of knowledge (based on mathematical knowledge) How does descartes think that knowledge should be expressed: believes there are two forms of expression, 2 types of statements, if there is knowledge, it has to be expressed in these two types, my shirt is white, 1+1=2. Modality (how the subject and predicate can be connected) Temporality (how long is it true time: my shirt is white. Verification: senses (empirical: even though the shirt is white, it can be altered, any empirical sentence can be falsified if circumstances justify, 1+1=2. If modality is necessity, it is impossible (logically, or physically) to separate the subject from the predicate. The subject is necessary and therefore, the subject and predicate are inseparable. In cases like my shirt is white, the temporality of empirical sentences are temporary because it will be false when the shirt is not white anymore.
