Based on the simulation and the case study, we propose some propositions about the factors and principles influencing the evolutionary complexity of CASNs.
In the spirit of this we may say that some propositions about the past are really (at any rate in part) about the future.
Russell (especially 1905a; see also 1905b and 1907) chiefly objects to Meinong's theory as inconsistent because of the following: (1) Some propositions about impossible objects (e.g., "The round square is round and not round") are contradictory.
Based on similarities between bacterial respiration and electrodic processes, we here present some propositions about microbial activities in electrochemical systems, which justify why microorganisms could interact with polarized surfaces and how these interactions could potentially be utilized for bioengineering as well as life science issues.
Geach's review sent Prior back to the ancient sources, and he found Aristotle describing some propositions about the future propositions concerning events that are not determined at the time of utterance as being neither true nor false when they are uttered, on the ground that there is, at that time, as yet no definite fact with which they accord or conflict.
If it is false, some other proposition about how many sentences Austen wrote that day is true.
For instance, a proposition which conjoins some plausibly necessary proposition about the past with a law of nature to the effect that in these circumstances something in the future will ensue would seem to entail something about the future; but since it is a conjunction of two plausibly necessary propositions, it seems to be necessary itself.
No matter: at all times, but especially in these times, it's a very good idea to ask, when some economist offers a proposition about the economy, "Um, how exactly is that supposed to work?" You'd be amazed how often no answer is forthcoming.
Thus Russell has set himself a rather difficult problem, since it is not at all clear that there can be any true propositions that are not, in some sense, propositions about what is, has been or will be.
