In this paper, we present a modality-free pre-rough algebra. Łukasiewicz Moisil algebra and Wajsberg algebra are equivalent under a transformation. A similar type of equivalence exists in our proposed definition and standard definition of pre-rough algebra. We obtain a few modality-free algebras weaker than pre-rough algebra. Furthermore, it is also established that modality-free versions for other analogous structures weaker than pre-rough algebra do not exist. Both Hilbert-type axiomatization and sequent calculi for all proposed algebras are presented.

In the case of agriculture and environment, the bioethical vision driven by altruistic principles includes the integral and differential domains of human ideas and its structural and functional analogies related to agroecology based decision making which results from the interplay among specific cultures, tradition, values and vision and being confronted with varied combinations of idea biosynthesis for survival. The integral reciprocity of idea biosynthesis probably can be postulated in a theory of "diverged convergence into divergence" and can be hypothesized as a two divergent -one convergent phenomena. Empirically we may try to derive a decision after taking into consideration many ideas wherein 'I' is a combination of Vn values in one point of neural flux.The chance of possible exploration of altruistic vision also throws light on to this issue about how these constants, if any, remain constant over a period of time 'n' or else there limit tends to be 'infinite' which is being propagated, inherited and mutated within every 'finite limit'.In this paper the authors are trying to hypothesize evolutionary perspectives of bioethics having its temporal and spatial variation specially in the case of agriculture and environment which is more explicitly focused. In the context of agriculture and environment the philosophical attributes might have been inherited in hand with religious practices and otherwise. And this is the crux of the agroecological decision theory per se for sustainable plant genetic resources and it is associated with the ecological domain and questions on ethics/morals/values for example bioethics by/for sustainability
