What is Morality?

Philosophy is, broadly speaking, divided into three general categories: metaphysics (what is the nature of existence and reality?), epistemology (what is knowledge and how is it possible?), and ethics (what is the nature of good and evil and how should people live their lives to accord with what is good?). It’s this latter one that tends to have the most practical impact on people’s lives. Indeed, things like business ethics, governmental ethics, medical ethics, bioethics, and so on are where the rubber really meets the road. Yet, they still fail to answer the very basic question of “what is good?” and “how should I live my life?” for our everyday, mundane situations.

Why do Humans Care About Fame?

/ Thomas Harper / 3 Comments

Humans seem to be evolutionarily predisposed towards interest in what other people are doing, since this has allowed for the social cohesion that’s been instrumental to our survival. There is also an element that, the more other people there are who care what a particular person says and does, the more people will care what that particular person says and does, creating a positive feedback loop. Social status in the form of notability must have developed as a way of attaining reproductive access.

A Critique of Critical Theory: the Insufficiency of Postmodernist Causal Explanation

/ Thomas Harper / Leave a comment

Critical Theory is a methodology of critiquing power relations within society. It takes as axiomatic the new-Marxist analysis of oppressor-oppressed dynamics being inherent in all human relationships. As such, Critical Theory is not about whether such power dynamics exist, but in what ways they manifest. There is little talk about why these dynamics manifest.

Poststructuralist Semiotics and Evolutionary Psychology

/ Thomas Harper / Leave a comment

Poststructuralism is a theory of semiotics (language and signs) that, broadly speaking, says that meaning is an effect of language, rather than a cause. In other words, what things mean to us is formed by language as opposed to our language having a 1-to-1 correspondence with reality. This theory, of course, takes the blank slate theory axiomatically. But what if we combine it with evolutionary psychology?

Structure of the Mind

/ Thomas Harper / 1 Comment

Consciousness and qualia are problems that are still unsolved by philosophy, psychology, and neuroscience. My way of viewing consciousness and qualia is that consciousness is the process by which our brains organize the world into working models and qualia is the ‘stuff’ that consciousness uses to generate those models. For better or worse, both of these exist due to evolutionary forces. That means they’re fine tuned to a very specific sort of survival, not for any pure understanding of the world or ourselves. In order to understand the limitations of our own minds, we need to know the inner workings of how the world is organized in our minds on a fundamental level. That requires knowing the structure of our minds.

A Primer on Evolution pt 2: Evidence

/ Thomas Harper / 4 Comments
evidence of evolution

In part two, I will give a brief overview of the evidence for the theory of evolution. This is not an exhaustive compendium of all the evidence in support of the theory of evolution. It is already a long post, so I keep all my descriptions brief. If you are interested in learning more, I provide plenty of links to websites and peer reviewed papers all throughout.

If you’re interested in how evolution relates to religion and whether it gives us any reason not to believe in God, check out this post. The current discussion will not touch on the subject, sticking strictly to the science.

A Primer on Evolution pt 3: Higher Concepts

evolutionary concepts

What follows are more conceptual aspects of evolution that build on the ideas discussed in the part 1. It’s not absolutely necessary, but I would recommend checking out part 2 first as well. In this conclusion to my three-part primer on evolution, I will discuss things like reproductive isolation, the different ways that evolution occurs, sexual selection, ecology, chaos theory, and evolutionary equilibrium. That evolution by natural selection has occurred and is occurring is not controversial in biology, which means most biologists are not actively searching for evidence that evolution by natural selection is a true phenomenon – the evidence that it is occurring is in. This post, therefore, introduces you to some of the areas of active research in evolutionary theory.
