INTRODUCTION

English translation pending.

CORE DEFINITION

A tradition running from Plato through Immanuel Kant. Moral rationalism holds that moral truths can be grasped by reason independently of emotion, revelation, or experience, and that a genuinely moral act must rest on a rational principle rather than on inclination. Kant's categorical imperative is its classic form: act only on maxims you could will to be universal laws. The position stands in direct contrast to moral intuitionism and emotivism.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Universalize the maxim: ask what would happen if everyone acted on the rule you are considering - Replace preference with principle: state the rule your decision follows, then test whether it holds for others - Separate reason from inclination: check whether the argument would stand if you did not want the conclusion

Anchor fast decisions

Reason can test a maxim for consistency by asking whether it could be adopted universally, and an inconsistent maxim destroys the practice it depends on. That test requires no particular desire, so its conclusion holds regardless of what the agent happens to want. Moral judgments grounded this way are therefore uniform across people rather than varying with preference.

Deontology

Deontological ethics (deontology) is one of the theories of normative ethics. It holds that the highest moral ethics is based on the action itself and is not influenced by external factors. Unlike utilitarianism, which is also a branch of normative ethics, deontology does not consider consequences. It is sometimes called 'duty-based' or 'rule-based' ethics, emphasizing that the objective basis of moral judgment is the 'good will', valuing the motive of action, and holding that one should do good unconditionally out of duty. A representative figure is Kant, whose theory has had a great influence on later deontological ethics.

The Forgetting Curve

The Forgetting Curve is a curve used to describe the rate of forgetting in long-term memory. It was first proposed by psychologist Hermann Ebbinghaus based on his experiments conducted from 1880 to 1885. In these experiments, Ebbinghaus used meaningless letter combinations. By memorizing these combinations and checking the forgetting rate after a series of time intervals, he obtained this curve. Therefore, this curve is also called the Ebbinghaus Forgetting Curve.
