Are verbs tensed or tenseless?

Conclusion We have seen that we cannot de-tense a sentence like (15) simply by changing its verb, since the tense of such a sentence is determined by a temporal adverb. More importantly, we have seen that de-tensing is a process of removing certain temporal restrictions from the truth-conditions of tensed sentences, and that tensed and tenseless forms of a verb do not differ in sense. Once we understand this, and once we realize that it is an historical accident that the tense of sentences in English if often indicated by means of the grammatical device of inflecting verbs, tensed verbs no longer seem to be the sort of item that needs to be purged from ordinary language in constructing its tenseless analogue. Indeed, although the distinction between tensed and tenseless verbs may still be of philosophic interest, this distinction hardly seems to deserve the pivotal role assigned to it in the literature.     

FINE'S MCTAGGART,TEMPORAL PASSAGE,AND THE A VERSUS B‐DEBATE

I offer an interpretation and a partial defense of Kit Fine's ‘Argument from Passage’, which is situated within his reconstruction of McTaggart's paradox. Fine argues that existing A‐theoretic approaches to passage are no more dynamic, i.e. capture passage no better, than the B‐theory. I argue that this comparative claim is correct. Our intuitive picture of passage, which inclines us towards A‐theories, suggests more than coherent A‐theories can deliver. In Finean terms, the picture requires not only Realism about tensed facts, but also Neutrality, i.e. the tensed facts not being ‘oriented towards’ one privileged time. However unlike Fine, and unlike others who advance McTaggartian arguments, I take McTaggart's paradox to indicate neither the need for a more dynamic theory of passage nor that time does not pass. A more dynamic theory is not to be had: Fine's ‘non‐standard realism’ amounts to no more than a conceptual gesture. But instead of concluding that time does not pass, we should conclude that theories of passage cannot deliver the dynamicity of our intuitive picture. For this reason, a B‐theoretic account of passage that simply identifies passage with the succession of times is a serious contender.     

The Invisible Thin Red Line

The aim of this paper is to argue that the adoption of an unrestricted principle of bivalence is compatible with a metaphysics that (i) denies that the future is real, (ii) adopts nomological indeterminism and (iii) exploits a branching structure to provide a semantics for future contingent claims. To this end, we elaborate what we call Flow Fragmentalism, a view inspired by Kit Fine's non-standard tense realism, according to which reality is divided up into maximally coherent collections of tensed facts. In this way, we show how to reconcile a genuinely A-theoretic branching time model with the idea that there is a branch corresponding to the thin red line, that is, the branch that will turn out to be the actual future history of the world.     

Wishing It Were Now Some Other Time

One of the most serious obstacles to accepting a tenseless view of time is the challenge posed by our experience of tense. A particularly striking example of such experience, pointed out by Schlesinger but largely overlooked in the literature, is the wish felt by probably all of us at some time or other that it were now some other time. Such a wish seems evidently rational to hold, and yet on a tenseless theory of time such a wish must be regarded as irrational, since it is logically impossible for the now to be located at some other time, there being no such thing as an objective now or present. In order to accommodate rationally such a belief, most protagonists of tenseless time twist the evident meaning of the wish. Oaklander, for example, misconstrues the wish in terms of my wanting to have different perceptions. Others, like Coburn, admit frankly that such a wish is rational only on a tensed theory of time but mistakenly reject that theory on grounds that at best constitute a defeater of an argument for a tensed view of time, rather than a defeater of the tensed view itself. the argument for a tensed view of time from the experience of tense remains undefeated.     

Fine's Fragmentalist Interpretation of Special Relativity

In “Tense and Reality”, Kit Fine ( 2005 ) proposed a novel way to think about realism about tense in the metaphysics of time. In particular, he explored two non‐standard forms of realism about tense (“external relativism” and “fragmentalism”), arguing that they are to be preferred over standard forms of realism. In the process of defending his own preferred view, fragmentalism, he proposed a fragmentalist interpretation of the special theory of relativity (STR), which will be our focus in this paper. After presenting Fine's position, we will raise a problem for his fragmentalist interpretation of STR. We will argue that Fine's view is in tension with the proper explanation of why various facts (such as the Lorentz transformations) obtain. We will then consider whether similar considerations also speak against fragmentalism in domains other than STR, notably fragmentalism about tense.     

Time reference through verb inflection in Turkish agrammatic aphasia

This study tested the production of tensed finite verbs and participles referring to the past and future in agrammatic speakers of Turkish. The agrammatic speakers did not make more time reference errors in tensed verbs than in participles. This is interesting because tense in general cannot therefore be the main problem, since time reference for participles lacking tense inflection is as difficult as for verbs with tense inflection. Besides that, the past tense/perfect aspect was found to be more difficult to produce for the agrammatic speakers than the future tense/imperfect aspect. None of the current theories on agrammatic deficits can explain why reference to the past/perfect aspect is more difficult than reference to future/imperfect aspect, although a similar finding was reported for Dutch by Bastiaanse [Bastiaanse, R. (2008). Production of verbs in base-position by Dutch agrammatic speakers: Inflection versus finiteness. Journal of Neurolinguistics, 21, 104-119]. We present a remoteness model of time reference to account for the data.     

Appropriate emotions and the metaphysics of time

Prior used our emotions to argue that tensed language cannot be translated by tenseless language. However, it is widely accepted that Mellor and MacBeath have shown that our emotions do not imply the existence of tensed facts. I criticise this orthodoxy. There is a natural and plausible view of the appropriateness of emotions which in combination with Prior’s argument implies the existence of tensed facts. The Mellor/MacBeath position does nothing to upset this natural view and therefore is not sufficient to block one drawing conclusions for the metaphysics of time from the nature of our emotions.     

Temporal Language and Temporal Reality

It has recently been argued that the new B-theory of time argues invalidly from the claim that tensed sentences have tenseless truth-conditions to the conclusion that temporal reality is tenseless. But while early B-theorists may have relied on some such inference, new B-theorists do not. Giving tenseless truth-conditions for tensed sentences is not intended to prove that temporal reality is tenseless. Rather it is intended to undermine the A-theorist's move from claims about the irreducibility of tensed language to the conclusion that temporal reality must be tensed. I examine how A-theorists have used facts about language in attempting to establish their conclusions about the nature of temporal reality. I take the recent work of William Lane Craig, and argue that he moves illicitly from facts about temporal language to his conclusion that temporal reality is tensed.     

Temporal existence and temporal location

We argue that sensitivity to the distinction between the tensed notion of being something and the tensed notion of being located at the present time serves as a good antidote to confusions in debates about time and existence, in particular in the debate about how to characterise presentism, and saves us the trouble of going through unnecessary epicycles. Both notions are frequently expressed using the tensed verb ‘to exist’, making it systematically ambiguous. It is a commendable strategy to avoid using that verb altogether in these contexts and to use quantification and a location predicate instead.

     

Time,tense and special relativity

In this essay I address the issue of whether Einstein's Special Theory of Relativity counts against a tensed or “A-series” understanding of time. Though this debate is an old one, it continues to be lively with many prominent authors recently arguing that a genuine A-series is compatible with a relativistic world view. My aim in what follows is to outline why Special Relativity is thought to count against a tensed understanding of time and then to address the philosophical attempts to reconcile the two theories. I conclude that while modern physics on its own does not rule out the possibility of a real A-series, the combination of Einstein's theory and the philosophical arguments against tense is decisive. The upshot is that the tenseless or “B-series” view of time is the best one.     

Tense And Temporal Semantics

Tenseless theories of time entail that earlierthan, later than and simultaneous with (i.e.,McTaggart's `B-series') are the only temporalproperties exemplified by events. Such theories oftencome under attack for being unable to satisfactorilyaccount for tensed language. In this essay I arguethat tenseless theories of time are capable of twofeats that critics, such as Quentin Smith, argue arebeyond their grasp: (1) They can coherently explainthe impossibility of translating all tensed sentencesby tenseless counterparts; (2) They can account forcertain obviously valid entailment relations betweentensed sentence types. In analyzing tensed entailmentrelations tenselessly, I favor a date analysis oftensed language over a token-reflexive theory. Theupshot is that tenseless theories of time are notundermined by the linguistic facts.     

Presentism and Actualism

Presentism, some say, is either the analytic triviality that the only things that exist now are ones that exist now or the obviously false claim that the only things that have ever existed or will are ones that exist now. I argue that the correct understanding of presentism is the latter and so understood the claim is not obviously false. To appreciate this one has to see presentism as strictly analogous to anti-Lewisean actualism. What this modal analogue makes evident is that singular tensed statements can have scope ambiguities and so can be thought of as true with the temporal operator represented by the tense read as having wide scope. Secondly, I argue that the analogy with the modal case also makes it clear that presentism must be understood as a thesis of the form: ‘the only things that have ever existed or ever will exist stand in relation R to this (present) utterance’, and is not a substantive topic for debate until relation R is characterized in non-temporal terms. However, despite the strict analogy, I argue that presentism may be a harder position to defend than actualism, since the truth-maker objection, properly interpreted, with Lewis, as based on a supervenience thesis, has more force as an objection to presentism since supervenience is itself a modal notion.

     

A Tenseless Account of the Presence of Experience

Tenseless theories of time entail that the only temporal properties exemplified by events are earlier than, simultaneous with, and later than. Such an account seems to conflict with our common experience of time, which suggests that the present moment is ontologically unique and that time flows. Some have argued that only a tensed account of time, one in which past, present and future are objective properties, can do justice to our experience. Any theory that claims that the world is different from how we experience it must nonetheless be consistent with the having of that experience. Accordingly, in this essay I defend the tenseless theory by arguing that it can indeed account for certain key features of our experience of time without recourse to tensed properties.     

Leibniz's non-tensed theory of time

Leibniz's philosophy of time, often seen as a precursor to current forms of relationalism and causal theories of time, has rightly earned the admiration of his more recent counterparts in the philosophy of science. In this article, I examine Leibniz's philosophy of time from a new perspective: the role that tense and non-tensed temporal properties/relations play in it. Specifically, I argue that Leibniz's philosophy of time is best (and non-anachronistically) construed as a non-tensed theory of time, one that dispenses with tensed temporal properties such as past, present, and future. In arguing for this thesis, I focus on the three facets of Leibniz's philosophy most relevant for evaluating his commitment to a B-theory of time: (1) the nature of change, (2) the reality of the future, and (3) the truth-conditions for tensed temporal statements. Despite prima facie evidence to the contrary, I show that a close examination of Leibniz's views on these topics provides compelling evidence for interpreting his philosophy of time as a B-theory of time.     

Overtensing and the effect of regularity

Regularly inflected forms often behave differently in language production than irregular forms. These differences are often used to argue that irregular forms are listed in the lexicon but regular forms are produced by rule. Using an experimental speech production task with adults, it is shown that overtensing errors, where a tensed verb is used in place of an infinitive, predominantly involve irregular forms, but that the differences may be due to phonological confounds, not to regularity per se. Errors involve vowel‐changing irregular forms more than suffixing inflected forms, with at best a small difference between regular ‐ed and irregular ‐en. Frequency effects on overtensing errors require a model in which the past‐tense and base forms of the verb are in competition and in which activation functions are nonlinear, and rule out models with specialized subnetworks for past‐tense forms. Implications for theories of language production are discussed.     

Smart and Tensed Beliefs

The aim of this paper is to defend a prototype B-theory answer to McTaggart’s Puzzle about Time. Smart hopes to solve the issue by pointing to the “anthropocentricity” of temporal A-notions. There is one important problem: explaining Prior cases (for instance being relieved that a painful experience is over) in B-theoretic terms. First, it is argued that the problem is how to explain the nature of the subject’s tensed belief in Prior cases; the essential indexicality of the concept ‘now’. Then it is suggested that Smart could utilize Burge’s framework for dealing with de re beliefs and a way of formalizing tensed beliefs is proposed. The last section of the paper deals with the exact role of the formalized indexical element. If these three steps are worked out, we might have an explanation of the facts involved in Prior cases without mentioning any A-facts. Hence an important problem to a Smart-influenced B-theory is solved, and McTaggart’s Puzzle answered in an adequate manner.     

Epistemic constraints on practical normativity

What is the relation between what we ought to do, on the one hand, and our epistemic access to the ought-giving facts, on the other? In assessing this, it is common to distinguish ‘objective’ from ‘subjective’ oughts. Very roughly, on the objectivist conception what an agent ought to do is determined by ought-giving facts in such a way that does not depend on the agent’s beliefs about, or epistemic access to, those facts; whereas on the subjectivist conception, what an agent ought to do depends on his beliefs. This paper defends the need for, and explicates, a third category of ‘ought’: ‘warranted oughts’. Section 1 introduces the distinction between objective and subjective ‘oughts’. Sections 2–3 draw attention to some serious problems with each. Section 4 examines, though rejects, a recent attempt to replace subjective ‘oughts’ with objective ‘wide-scope oughts’ operating on belief-action combinations. Section 5 explicates the notion of a warranted ‘ought’ and defends the account against some possible objections. The resulting a picture is one in which an adequate analysis of practical normativity requires both objective and warranted ‘oughts’. Section 6 concludes by responding to a worry about countenancing both.

     

Folk Platitudes as the Explananda of Philosophical Metaethics: Are They Accurate? And Do They Help or Hinder Inquiry?

The field of metaethics, the branch of moral philosophy that examines the nature and status of morality, is rich in theoretical diversity. Nonetheless, a majority of professional philosophers embrace a subset of theories that affirm the existence of objective moral facts. I suggest that this may be related to the very method that philosophers use to construct metaethical theories. This method involves analyzing how ordinary people think and argue about morality. Analysis of ordinary moral discourse is meant to reveal common platitudes (or truisms) about the nature of morality itself, including the platitude that morality trades in objective moral facts. But do philosophers investigate ordinary moral discourse in any systematic way? How do they arrive at such platitudes? On what grounds are they justified? In this paper, I critically examine these questions and argue that a) any such platitudes need to be investigated systematically through empirical research and b) philosophers ought to be engaged in this research themselves.

     

Now is the time

The aim of this paper is to consider some logical aspects of the debate between the view that the present is the only ‘real’ time, and the view that the present is not in any way metaphysically privileged. In particular I shall set out a language of first-order predicate tense logic with a now predicate, and a first order (extensional) language with an abstraction operator, in such a way that each language can be shewn to be exactly translatable into the other. I shew that this translation is preserved at the metalinguistic level, so that equivalent truth conditions can be defined in a tensed metalanguage or an indexical metalanguage. I then make some remarks about the connection between proofs of relative consistency and metaphysical truth; and some historical remarks about Arthur Prior's use of formal logic in expressing his presentist views.     

Truth-conditions,truth-bearers and the new B-theory of time

In this paper I consider two strategies for providing tenseless truth-conditions for tensed sentences: the token-reflexive theory and the date theory. Both theories have faced a number of objections by prominent A-theorists such as Quentin Smith and William Lane Craig. Traditionally, these two theories have been viewed as rival methods for providing truth-conditions for tensed sentences. I argue that the debate over whether the token-reflexive theory or the date theory is true has arisen from a failure to distinguish between conditions for the truth of tensed tokens and conditions for the truth of propositions expressed by tensed tokens. I demonstrate that there is a true formulation of the token-reflexive theory that provides necessary and sufficient conditions for the truth of tensed tokens, and there is a true formulation of the date theory that provides necessary and sufficient conditions for the truth of propositions expressed by tensed tokens. I argue that once the views are properly formulated, the A-theorist’s objections fail to make their mark. However, I conclude by claiming that even though there is a true formulation of the token-reflexive theory and a true formulation of the date theory, the New B-theory nonetheless fails to provide a complete account of the truth and falsity of tensed sentences.
