    Freedom, Foreknowledge, and Dependence: A Dialectical Intervention

    Recently, several authors have utilized the notion of dependence to respond to the traditional argument for the incompatibility of freedom and divine foreknowledge. However, proponents of this response have not always been so clear in specifying where the incompatibility argument goes wrong, which has led to some unfounded objections to the response. We remedy this dialectical confusion by clarifying both the dependence response itself and its interaction with the standard incompatibility argument. Once these clarifications are made, it becomes clear both (1.) that the dependence response does not beg the question against the proponent of the incompatibility argument and (2.) that the dependence response advances the dialectic whether it is developed as a version of Ockhamism or as a version of multiple-pasts compatibilism

    Explaining Classifiers using Adversarial Perturbations on the Perceptual Ball

    We present a simple regularization of adversarial perturbations based upon the perceptual loss. While the resulting perturbations remain imperceptible to the human eye, they differ from existing adversarial perturbations in that they are semi-sparse alterations that highlight objects and regions of interest while leaving the background unaltered. As a semantically meaningful adverse perturbations, it forms a bridge between counterfactual explanations and adversarial perturbations in the space of images. We evaluate our approach on several standard explainability benchmarks, namely, weak localization, insertion deletion, and the pointing game demonstrating that perceptually regularized counterfactuals are an effective explanation for image-based classifiers.Comment: CVPR 202

    Influence of post-exercise nutrient intake on recovery and subsequent exercise performance in youth cyclists

    Purpose: The purpose of this study was to determine if chocolate milk (CM) consumption after high-intensity cycling exercise affects post-exercise recovery and subsequent exercise performance in youth cyclists, compared to a carbohydrate-only (CHO) and a placebo (PL) beverage. Methods: Eight youth cyclists (15-18 y, VO2peak = 61.8 ± 7.7 mL·kg-1·min-1) performed an exercise/recovery protocol consisting of 2 bouts of exercise, on 3 separate occasions, in a randomly counterbalanced crossover design. The first exercise bout (EX1) consisted of 30 min of constant-load cycling (40-60% Wmax), and 60 min of high-intensity intervals (alternating 2 min at 70-90% Wmax, 2 min at 50% Wmax). Subjects consumed a recovery beverage (PL, CHO or CM) immediately following EX1 and again 2 h after EX1. EX2 consisted of 30 min of constant-load cycling (60% Wmax) followed by a simulated 30 km time trial (TT). Ratings of muscle soreness and mental and physical energy/fatigue were obtained prior to EX1, 4 h post-EX1, and pre-EX2. Results: Changes in muscle soreness ratings over time were not significantly different between treatments. However, within the PL trial, soreness was significantly elevated from pre-EX1 to 4 h post-EX1 and pre-EX2 (pre-EX1, 4h-post, pre-EX2 = 44.1 ± 23.1, 67.4 ± 22.2, 68.3 ± 19.6 mm, respectively. Physical fatigue ratings increased significantly from pre-EX1 to pre-EX2 in PL. In addition, changes in physical fatigue 4 h following EX1 were greater in CHO than CM, with no other significant within- or between-treatment effects in energy/fatigue ratings. Average power during the TT was not significantly different between treatment trials (PL: 181 ± 27, CHO: 197 ± 39, CM: 195 ± 38 W) (p = 0.23 CHO vs. PL; 0.19 CM vs. PL). Conclusion: CM ingestion after exercise may confer some recovery benefits in youth cyclists, as demonstrated by the absence of elevated post-exercise muscle soreness and energy/fatigue ratings in the CM trials. CM ingestion did not significantly improve subsequent cycling performance when compared to CHO or PL beverages. Subsequent research should utilize larger sample sizes to provide more conclusive evidence to enhance the knowledge regarding the impact of CM as a recovery method for youth cyclist

    Incompatibilism and the garden of forking paths

    Let (leeway) incompatibilism be the thesis that causal determinism is incompatible with the freedom to do otherwise. Several prominent authors have claimed that incompatibilism alone can capture, or at least best captures, the intuitive appeal behind Jorge Luis Borges's famous “Garden of Forking Paths” metaphor. The thought, briefly, is this: the “single path” leading up to one's present decision represents the past; the forking paths that one must decide between represent those possible futures consistent with the past and the laws of nature. But if determinism is true, there is only one possible future consistent with the past and the laws and, hence, only one path to choose from. That is, if determinism is true, then we are not free to do otherwise. In this paper, I argue that this understanding of the Garden of Forking Paths faces a number of problems and ought to be rejected even by incompatibilists. I then present an alternative understanding that not only avoids these problems but still supports incompatibilism. Finally, I consider how various versions of (leeway) compatibilism fit with the Garden of Forking Paths as well as the broader question of whether metaphors, however intuitive, have any dialectical force in the debates over freedom
