Author’s aim is to highlight problems related to the course of regulatory processes in the structures of the living organism. In this research area the question arises what is the task of causal factors and mechanisms governing regeneration processes, including building new parts of the body. Despite the vast knowledge already gained in this field, the way to restore the functional regeneration of some structures of the organism is still to be discovered.

The aim of the paper is to highlight St. Anselm’s way of thinking about nature and order in the world created by God. God for Anselm is the highest nature, one which exists most fully; He possesses the fullness of being, because His essence is identical to His existence. He is the cause of all existing things and does not have a cause Himself, for He exists per se. The order of nature may be observed in two ways: when departing from the diversity of existing beings and when considering these beings before their creation, existing in the divine intellect as ideas and models, after which God called into existence particular objects.

The term “cause” is ubiquitous in life and science. It is surprising how, generally speaking, the existing all-purpose dictionaries, and even «professional» ones, are clumsy in their attempts to define “cause” and its derivative terms. We urgently need a more satisfactory definition of these words, along the following lines: an acting of object x on object y is the cause of the change in object y, when at the same time object x acts on object y, object y changes, and if something of the type of object x acts on an object of the type of object y, then object y changes. When expanding the proposed definition, I consider, among others: (a) traditional counterarguments aimed at the existence of cause-effect relation, (b) the question of necessity as a component of the notion of causality, (c) the notion of acting on something and the circumstances of its occurrence, (d) the essence of change, and (e) the causality principle. In addition, I sketch the relation of the reconstructed notion of causality to the notions of motivation, perpetration, and the act of creation (in arts and in Catholicism).

The main goal of the paper is to show the value of texts preserved in more than one version for studies aimed at identifying reasons for the demise of words. The data selected is a set of six non-surviving English preterite-present verbs. The analysis of the material shows that mediaeval manuscripts often exhibit orthographic and morphological variation as well as differ in lexemes. Such differences prove to be useful for the search of factors leading to the elimination of the verbs in question.
