    Functional Explanation in Biology.Hugh Lehman - 1965 - 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 (...)

    Are Biological Species Real?Hugh Lehman - 1967 - 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 (...)

    Ethics and Farm Animal Welfare.J. F. Hurnik & Hugh Lehman - 1988 - 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 (...)

  6. Assessment of GM Crops in Commercial Agriculture.E. Ann Clark & Hugh Lehman - 2001 - 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 (...)

  7. Statistical Explanation.Hugh Lehman - 1972 - 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 (...)

    Rationality and Ethics in Agriculture.Hugh Lehman - 1995 - Moscow: University of Idaho Press.
    Distributed by the University of Nebraska Press for the University of Idaho Press Explores contemporary social criticism of agriculture by analyzing assumptions regarding matters such as animal welfare, biotechnology, ethics and human nature. Dr. Lehman carefully investigates the various meanings and criteria of "rational" without presupposing prior knowledge of philosophy, making the material accessible to students, agriculture scientists, and members of the public concerned with agriculture.

    On the Moral Acceptability of Killing Animals.Hugh Lehman - 1988 - 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.

    Mathematical Proofs, Gaps and Postulationism.Hugh Lehman - 1984 - The Monist 67 (1):108-114.
    In a recent paper, the mathematician Harold Edwards claimed that Euler’s alleged proof, that Fermat’s last theorem is true for the case n = 3, is flawed. Fermat’s last theorem is the conjecture that there are no positive integers x, y, z, or n, such that n is greater than two and such that xn + yn = zn. In this paper we shall first briefly explain the specific flaw to which Edwards called attention. After that we briefly explain the (...)

    Intuitionism and Platonism on Infinite Totalities.Hugh Lehman - 1983 - Idealistic Studies 13 (3):190-198.
    Mathematical objects, according to intuitionists, exist only in the mind of the mathematician. Such objects are, in reality, structures which are created by the mathematician. Creation of such structures is limited by the capability of the mind to generate sequences of objects. Knowledge of mathematical objects or structures is possible through the mind’s capability to survey or inspect the structures that it has created. The platonist, contrary to the intuitionist, maintains that mathematical objects have an existence which is not causally (...)

    R. K. Merton's Concepts of Function and Functionalism.Hugh Lehman - 1966 - Inquiry: An Interdisciplinary Journal of Philosophy 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.

    Farming Salmon Ethically.E. A. Needham & Hugh Lehman - 1991 - Journal of Agricultural and Environmental Ethics 4 (1):78-81.
    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.

    Equal Pay for Equal Work in the Third World.Hugh Lehman - 1985 - Journal of Business Ethics 4 (6):487 - 491.
    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.
