"Wise men are intelligent" This is a priori of course because the concept of intelligence in predicate is contained in the concept of wise man. let's twist it a little and find an analytic a posteriori statement like this, "wise men were (in past) more intelligent than now. It will take your time to measure the difference between old time's wise men and the present day's by watc... Read more →
One difficulty concerns the status of concepts within the entity called a proposition, and this arises from his doctrine that any quality or absence of quality presupposes being . On Russell’s view the difference between a concept occurring as such and occurring as a subject term in a proposition is merely a matter of their external relations and not an intrinsic or essential difference in entities ( Principles , p. 46). Hence a concept can occur either predicatively or as a subject term. He therefore views with suspicion Frege’s doctrine that concepts are essentially predicative and cannot occur as objects, that is, as the subject terms of a proposition ( Principles , Appendix A). As Frege acknowledges, to say that concepts cannot occur as objects is a doctrine that defies exact expression, for we cannot say “a concept is not an object” without seemingly treating a concept as an object, since it appears to be the referent of the subject term in our sentence. Frege shows little distress over this problem of inexpressibility, but for Russell such a state of affairs is self-contradictory and paradoxical since the concept is an object in any sentence that says it is not. Yet, as he discovers, to allow concepts a dual role opens the way to other contradictions (such as Russell’s paradox), since makes it possible for a predicate to be predicated of itself. Faced with paradoxes on either side, Russell chooses to risk the paradox he initially sees as arising from Frege’s distinction between concepts and objects in order to avoid more serious logical paradoxes arising from his own assumption of concepts’ dual role. (See Principles , Chapter X and Appendix B.) This issue contributes to his emerging attempt to eliminate problematic concepts and propositions from the domain of what has being. In doing so he implicitly draws away from his original belief that what is thinkable has being, as it is not clear how he can say that items he earlier entertained are unthinkable.

'First published in German in 1984 as volume 45 of Martin Heidegger's collected works, this book translates a lecture course he presented at the University of Freiburg in 1937-1938. Heidegger here raises the question of the essence of truth, not as a "problem" or as a matter of "logic", but precisely as a genuine philosophical question, in fact the one basic question of philosophy. Thus, this course is about the intertwining of the essence of truth and the essence of philosophy. On both sides Heidegger draws extensively upon the ancient Greeks, on their understanding of truth as aletheia and their determination of the beginning of philosophy as the disposition of wonder. In addition, these lectures were presented at the time that Heidegger was composing his second magnum opus, Beiträge zur Philosophie , and provide the single best introduction to that complex and crucial text.'
Bergson’s ideas concerning the philosophy of time were somewhat rediscovered after a paper on Zeno’s paradox was published in Foundations of Physics Letters and generated interest in 2003. The writer, Peter Lynds, was credited with producing an original new insight.  However, it was noted in a journal article shortly after that the ideas in this paper were preceded by Henri Bergson, evidently unbeknownst to Lynds or his paper's referees.
