    Hugh Lehman (1972). Statistical Explanation. Philosophy of Science 39 (4):500-506.
    Wesley Salmon has advanced a new model of explanations of particular facts which requires that the explanans contain laws. The laws used in explanations (according to this model) are of the form P(A· C1,B)=p1... P(A· Cn,B)=pn. A condition imposed by Salmon on these laws is that the reference classes, i.e. A· C1... A· Cn, be homogenous with reference to the property B. A reference class A is homogenous with reference to a property B if every property which determines a place (...)

    Hugh Lehman (1988). On the Moral Acceptability of Killing Animals. Journal of Agricultural and Environmental Ethics 1 (2):155-162.
    According to a rights view it is acceptable to kill animals if they are innocent threats or shields or are in a lifeboat situation. However, according to advocates of such a view, our practices of killing animals for food or scientific research may be morally unacceptable. In this paper we argue that, even if we grant the basic assumptions of a rights view, a good deal of killing of animals for food and scientific research continues to be morally acceptable.

    Hugh Lehman (1966). R. K. Merton's Concepts of Function and Functionalism. Inquiry 9 (1-4):274 – 283.
    In this paper an attempt is made to provide an analysis of the meaning of the term function and related terms as they are used by R. K. Merton in the first chapter of his book Social Theory and Social Structure. Several problems are suggested which must be solved if statements about functions are to be considered scientifically adequate. Secondly the term functionalism is defined and several of Merton's functionalist explanations of social phenomena are stated and criticized.

    J. F. Hurnik & Hugh Lehman (1988). Ethics and Farm Animal Welfare. Journal of Agricultural and Environmental Ethics 1 (4):305-318.
    In this paper the authors argue that ethical considerations are relevant for evaluating animal production systems and that in consequence agrologists should seriously consider the arguments of animal welfare supporters. Furthermore, the authors point out the ethical basis for some (though not all) of the conclusions proposed by supporters of animal welfare. In consequence it is necessary to determine the nature of animal welfare and methods of evaluating the welfare of animals and to recognize when production systems fail to satisfy (...)

    Hugh Lehman (1967). Are Biological Species Real? Philosophy of Science 34 (2):157-167.
    Difficulties with the typological concept of species led biologists to reject the "typological" presupposition of an archetype which is manifest in each member of a species. The resulting concept of species, which is here called the phenotypic species concept, is considered as implying that biological species are not real. Modern population thinking has given rise to the concept of a species as a gene-pool. This modern concept is contrasted here with the phenotypic concept in light of some general criteria for (...)

    E. Ann Clark & Hugh Lehman (2001). Assessment of GM Crops in Commercial Agriculture. Journal of Agricultural and Environmental Ethics 14 (1):3-28.
    The caliber of recent discourse regarding geneticallymodified organisms (GMOs) has suffered from a lack of consensuson terminology, from the scarcity of evidence upon which toassess risk to health and to the environment, and from valuedifferences between proponents and opponents of GMOs. Towardsaddressing these issues, we present the thesis that GM should bedefined as the forcible insertion of DNA into a host genome,irrespective of the source of the DNA, and exclusive ofconventional or mutation breeding.Some defenders of the commercial use of GMOs (...)

    Hugh Lehman (1965). Functional Explanation in Biology. Philosophy of Science 32 (1):1-20.
    This paper is concerned with the problem of giving a correct analysis of function statements as they are used in biology. Examples of such statements are (1) The function of the myelin sheath is to insulate the nerve fiber and (2) The function of chlorophyll is to enable photosynthesis to take place. After criticizing analyses of such statements developed by Braithwaite, Nagel and Hempel an analysis is presented by the author. Finally the question of whether function statements are explanations is (...)

    Some writers have suggested that it would be desirable to assess the state of the Earth''senvironments by making use of a concept of ecosystem health. We subject this suggestion toscrutiny first by calling attention to obscurities inthe notion of an ecosystem and then by callingattention to obscurities in and objections to someviews about ecosystem health. Finally, we note, thateven if ecosystem health can be adequately clarified, there are reasons for saying that whetherwe are morally obligated to protect the health ofsome (...)

    If the principle of equal pay for work of equal value is valid, then the practice of paying workers in third-world countries at a lower rate than workers doing the same jobs in industrialized nations is unjust. Recently Henry Shue argued that the principle is not valid. In this paper I criticize Shue's arguments and offer additional arguments in support of his conclusion.

    Salmon farming is a rapidly expanding industry. In order for it to develop in an ethical manner, many ethical issues must be confronted. Among these are questions regarding the quality of life of salmon on farms. To develop reasonable answers to these questions considerable thought must be devoted to developing appropriate standards of care for salmon. If these questions are not addressed the results could be bad both for salmon and for salmon farmers.

    A number of distinct definitions ofsustainable agriculture have been proposed. In this paper we criticize two such definitions, primarily for conflating sustainability with other objectives such as economic viability and ecological integrity. Finally, we propose and defend a definition which avoids our objections to the other definitions.
