Descartes affords several notions of consciousness as he explains the characteristics of the diverse features of human thought from infancy to adulthood and from dreaming to attentive wakefulness. The paper argues that Descartes has a rich and coherent view of conscious mentality from rudimentary consciousness through reflexive consciousness to consciousness achieved by deliberate, attentive reflection.

It is plausible to think that before the emergence of terms like “consciousness” and “Bewusstsein,” philosophers and scientists relied on intuitions about phenomena of subjective experience that we would now classify as “conscious.” In other words, pre-modern thinkers availed themselves of one or another concept of consciousness as they developed their theories of mind, perception, representation, the self, etc., although they did not attend to consciousness in its own right. In the early modern period, terminology of consciousness emerges to pick (...) out concept(s) of consciousness. This brings with it an occasion for philosophical disagreements concerning consciousness among contemporaries, on the one hand, and an occasion for us as interpreters of historical authors to better assess their views on consciousness, on the other.

As Locke claims that consciousness of our being is involved in all thought and perception, he treats all consciousness as some type of self-consciousness. I examine how consciousness relates to what it is about by inquiring into the intimate relations between consciousness and mental acts and consciousness and the self.

Locke endorses a distinction between passive reflection and voluntary attentive reflection, which he occasionally labels contemplation. Failure to recognize this distinction properly has had an effect on interpretations of Locke’s theory of reflection, and caused puzzlement about the relation between reflection and consciousness. In particular, the function of reflection as a passive internal sense that produces simple ideas of mental operations has been downplayed in favour of the view that reflection in one manner or another involves attention and/or presupposes consciousness (...) of mental operations. This has led a number of scholars to maintain, implicitly or explicitly, that Locke in fact abandons either his doctrine of sensation and reflection as the two exclusive sources of ideas or his doctrine of ideas as the only immediate objects of experience. -/- With the help of a distinction between reflection as a source of ideas and reflection as an operation about ideas I aim to show how Locke can hold to his empiricist maxim about the two sources of ideas and also endorse ideas as the only immediate objects of experience. A proper understanding of Locke’s theory of reflection requires that reflection and consciousness be delineated with respect to one another. I will show how Locke’s notion of consciousness differs from both types of reflection. (shrink)
