Kant and the Neglected Alternative
In this work, I conduct a reconstruction and evaluation of the Neglected Alternative objection to Immanuel Kant\u27s philosophy. Kant famously argues in the Transcendental Aesthetic section of the Critique of Pure Reason that space and time are subjective forms of human intuition, and the Neglected Alternative maintains that this argument is a failure. According to the Neglected Alternative, Kant completely overlooks the possibility that space and time are in some way both subjective and objective, and so Kant\u27s conclusions about the nature of space and time are not justified by his arguments. This objection was first formulated very soon after the publication of the Critique of Pure Reason but is still subject to great controversy among Kant scholars.
I argue that the Neglected Alternative objection is unsuccessful. To do this, I provide a close analysis of Kant\u27s key technical term a priori intuition, and I reconstruct the work of two important critics of Kant: H.A. Pistorius and F.A. Trendelenburg. I then argue that in the Transcendental Aesthetic, Kant is justified in deriving the conclusion that space and time have nothing to do with things in themselves, or objects entirely independent of human cognition. Finally, I look at Kant\u27s works as a whole and consider Kant\u27s arguments that seem to rule out the possibility that things in themselves have a structure that is even similar to space and time
Immature stages of Spodoptera eridania (Lepidoptera: noctuidae): developmental parameters and host plants.
This study aimed to detail the temporal and morphological parameters of the immature stages of southern armyworm Spodoptera eridania (Stoll, 1782) with larvae feed on artificial diet, under controlled conditions (25?±?1°C, 70?±?10% relative humidity and 14-h photophase) and gather information about their larval host plants. The viability of the egg, larval, pupal, and prepupal stages was 97.82, 93.62, 96.42, and 97.03%, respectively. The average duration of the egg, larval, pupal, and pre-pupal stages was 4.00, 16.18, 1.58, and 9.17 d, respectively. During the larval stage, 43.44% of females passed through seven instars, observing that the female's development was significant slower than males. The female larvae that developed through six and seven instars exhibited a mean growth rate of 1.52 and 1.44, respectively. Female pupae were significantly larger, exhibiting faster development than males. The rearing method proved to be adequate, providing more detailed observations of the biological cycle, especially at the larval stage, and resulting in an overall survival of almost 85%. Two hundred two plant species belonging to 58 families are listed as natural hosts for S. eridania, mainly including Asteraceae, Fabaceae, Solanaceae, Poaceae, Amaranthaceae, and Malvaceae
Rationality of quotients by linear actions of affine groups
Let G be the (special) affine group, semidirect product of SL_n and C^n. In
this paper we study the representation theory of G and in particular the
question of rationality for V/G where V is a generically free G-representation.
We show that the answer to this question is positive if the dimension of V is
sufficiently large and V is indecomposable. We have a more precise theorem if V
is a two-step extension 0 -> S -> V -> Q -> 0 with S, Q completely reducible.Comment: 18 pages; dedicated to Fabrizio Catanese on the occasion of his 60th
