This is an exploration of modernism and postmodernism in regard to knowledge: methods of inquiry, operations of the mind, the role of values, conceptions of self, and the problematic of reason.

Two groups of plant viruses have DNA in their genomes. One group, the caulimoviruses, are non‐integrating retroviruses that package dsDNA in virions. The other group, the geminiviruses, package small circular ssDNA and include the only DNA viruses known with bipartite genomes. The regulation of transcription of these viruses is not well characterized, but recent work is beginning to yield interesting results. Regulatory sequences from these viruses function in cells of species that are not hosts of the virus and are finding (...) use in constitutive expression of chimeric genes in transformed plants. Development of vectors based on plant viruses requires further characterization at the molecular level of viral life cycles. (shrink)

Let me begin by saying that this is an admirable collection, one that lives up to its title. William James, perhaps uniquely, is a philosopher who invites the companionship of others. One by one, the authors of these essays have accepted his invitation, each entering into a conversation with him. Ruth Anna Putnam has brought together a varied and interesting collection of essays; and I strongly recommend it both to specialists and to readers who may not yet be familiar with (...) his work.
