    Collective Essence and Monotonicity.Justin Zylstra - 2019 - Erkenntnis 84 (5):1087-1101.
    This paper focuses on the concept of collective essence: that some truths are essential to many items taken together. For example, that it is essential to conjunction and negation that they are truth-functionally complete. The concept of collective essence is one of the main innovations of recent work on the theory of essence. In a sense, this innovation is natural, since we make all sorts of plural predications. It stands to reason that there should be a distinction between essential and (...)

  2. Essence, Necessity, and Definition.Justin Zylstra - 2019 - Philosophical Studies 176 (2):339-350.
    What is it for something to be essential to an item? For some time, it was standard to think that the concept of necessity alone can provide an answer: for something to be essential to an item is for it to be strictly implied by the existence of that item. We now tend to think that this view fails because its analysans is insufficient for its analysandum. In response, some argue that we can supplement the analysis in terms of necessity (...)

  3. The Essence of Grounding.Justin Zylstra - 2019 - Synthese 196 (12):5137-5152.
    I develop a reduction of grounding to essence. My approach is to think about the relation between grounding and essence on the model of a certain conceptof existential dependence. I extend this concept of existential dependence in a coupleof ways and argue that these extensions provide a reduction of grounding to essenceif we use sorted variables that range over facts and take it that for a fact to obtain is forit to exist. I then use the account to resolve various (...)

    Constitutive and Consequentialist Essence.Justin Zylstra - 2019 - Thought: A Journal of Philosophy 8 (3):190-199.
    Recent work on essence describes essence as assimilated to definition. It also posits a plurality of kinds of essence.Howdoes assimilation relate to pluralism? According to one view, a kind of essence is adequate only if it is definitional: something is essential to an item, in the relevant sense, only if it is part of what it is to be that item. In this paper, I argue that assimilation and pluralism are in tension with respect to consequentialist essence. This is problematic (...)

    Dependence and Fundamentality.Justin Zylstra - 2014 - Studia Philosophica Estonica 7 (2):5.
    I argue that dependence is neither necessary nor sufficient for relative fundamentality. I then introduce the notion of 'likeness in nature' and provide an account of relative fundamentality in terms of it and the notion of dependence. Finally, I discuss some puzzles that arise in Aristotle's Categories, to which the theory developed is applied.
