A friend writes to mention an online open access journal, Cosmos and History:
Cosmos and History: The Journal of Natural and Social Philosophy is a peer-reviewed, open-access journal of natural and social philosophy. It serves those who see philosophy’s vocation in questioning and challenging prevailing assumptions about ourselves and our place in the world, developing new ways of thinking about physical existence, life, humanity and society, so helping to create the future insofar as thought affects the issue. Philosophy so conceived is not exclusively identified with the work of professional philosophers, and the journal welcomes contributions from philosophically oriented thinkers from all disciplines.

For example, An Introduction to Mathematical Metaphysics by Chris Langan:
ABSTRACT: Since the time of Aristotle, metaphysics has been an ill-defined term. This paper defines it as a logically idempotent metalinguistic identity of reality which couples the two initial ingredients of awareness: perceptual reality (the basis of physics), and cognitive-perceptual syntax, a formalization of mind. The explanation has been reduced to a few very simple, clearly explained mathematical ingredients. This paper contains no assumptions or arguable assertions, and is therefore presented as an advanced formulation of logic which has been updated for meaningful reference to the structure of reality at large. This structure, called the Cognitive-Theoretic Model of the Universe or CTMU, resolves the problems attending Cartesian dualism by replacing dualism with the mathematical property of self-duality, meaning (for reality-theoretic purposes) the quantum-level invariance of identity under permutation of objective and spatiotemporal data types. The CTMU takes the form of a global coupling or superposition of mind and physical reality in a self-dual metaphysical identity M:L U, which can be intrinsically developed into a logico-geometrically self-dual, ontologically self- contained language incorporating its own medium of existence and comprising its own model therein.
