There was no conceptual problem about the fact that the obligation of confidence was imposed only in respect of a particular form of information, namely, photographic images.

Leaving aside certain obvious errors, corrections made by an amendment did not raise any serious conceptual problem.

Only at the end do imyaslavie, and conceptual problems to do with 'naming' generally, make a brief reappearance.

This was a highly problematic notion, but even if the conceptual problems could be ironed out, scientists generally - certainly anatomists and botanists, but also physicists - needed representations.

One or two conceptual problems there, maybe.
